As described above, a photocatalytic technique can be cited as a representative technique for protecting the substrate from contaminants that affect the substrate from the outside. On the other hand, in the patent document 1, the applicant discloses a technique of generating a positive charge on the surface of the substrate by disposing a conductor and a composite of a dielectric or a semiconductor on the surface of the substrate or the surface layer of the substrate, so as to be externally charged. Contaminants are electrostatically adsorbed or repelled, thereby protecting the surface of the substrate. Further, the applicant disclosed in Patent Document 2 that the surface of the substrate is positively charged and negatively charged by the arrangement of the positively-charged substance and the negatively-charged substance on the surface of the substrate or the surface layer of the substrate, so that the pollutants from the outside are The surface of the substrate is electrostatically adsorbed or repelled, thereby protecting the surface of the substrate. Further, in this technique, the band voltage on the surface of the substrate generated by the positively-charged substance and/or the negatively-charged substance disposed on the surface of the substrate or the surface layer of the substrate functions as a function of protecting the substrate as described above. However, for example, even if the technology is implemented on the surface of an electronic device, it is only a weak band voltage that does not impair the function of the electronic device itself.

Further, in the above document, as one of methods for disposing a positively-charged substance or a negatively-charged substance on a surface of a substrate or a surface layer of a substrate, it is disclosed that a film-forming liquid having a positively-charged substance and/or a negatively-charged substance is used in the substrate. A method in which a film or a layer is formed on the surface is effective. On the other hand, in order to effectively exert the function of electrostatically repelling or adsorbing pollutants from the outside by charging the surface of the substrate or the surface layer of the substrate, it is required to dispose not only the positively or negatively charged substances but also the electric charges. It is formed efficiently, stably and stably in the surface of the substrate or in the surface layer of the substrate. Here, in order to avoid localization of charges formed on the surface of the substrate or the surface layer of the substrate, one of the solutions is to appropriately interpose a dielectric or semiconductor for stably forming charges between substances having conductivity. Further, it is necessary to solve the problem that a suitable substance is selected as the dielectric or semiconductor in terms of function or cost, thereby realizing a charge for stably forming and fixing and functioning a charge on a surface or a surface layer of a substrate.

為了使形成於基體表面或基體表面層之膜或層更有效地發揮使來自外部之污染物質靜電性地排斥或者吸附之功能,理想的是於基體表面或表面層形成粒子狀積層物,且於該粒子狀積層物規則地取入經乾燥固化之粒子,而形成有均一且均等之電荷。例如,作為此種粒子狀積層物之較佳例,可列舉以下之(a)~(c)。

(c)具有正電荷之物質及/或具有負電荷之物質與氧化鈦及/或氧化矽以作為分子等級之複合體之鈣鈦礦型或鈣鈦礦型擬晶粒之形式進行粒子接合而成之基體表面膜或表面層 上述形成於基體表面或表面層之粒子狀積層物之粒徑較佳為0.1 nm~100 nm。又,該積層物之層厚無特別限定,較佳為10 nm~1 μm之範圍,更佳為10 nm~100 nm之範圍。關於電荷形成之原理 以下,使用圖5及圖6,主要對如上述(a)所記載之藉由形成於基體表面或基體表面層之粒子狀積層物而對基體表面或者基體表面層賦予正電荷、負電荷、或者正電荷及負電荷之電荷形成之原理進行說明。 圖5(1)、圖5(2)、圖5(3)係模式性表示使用具有正電荷之物質及/或具有負電荷之物質與作為介電體或半導體之氧化鈦或氧化矽(包含該等之化合物),對基體表面或基體表面層分別賦予正電荷、負電荷、正電荷及負電荷之原理之圖。圖5(1)中,於具有正電荷之導電體之粒子AP與作為介電體或半導體之氧化鈦或氧化矽(包含該等之化合物)之粒子BB鄰接之狀態下在基體表面或基體表面層形成有膜或層,圖5(2)中,於具有負電荷之導電體之粒子AN與作為介電體或半導體之氧化鈦或氧化矽(包含該等之化合物)之粒子BB鄰接之狀態下在基體表面或基體表面層形成有膜或層,圖5(3)中,於具有負電荷之導電體之粒子AN與具有正電荷之導電體之粒子AP交替地鄰接於作為介電體或半導體之氧化鈦或氧化矽(包含該等之化合物)之粒子BB之狀態下在基體表面或基體表面層形成有膜或層。導電體在能夠自由地於內部移動之自由電子為高濃度下存在,藉由激發而使電洞(hole)或負之電子集中於造膜或者形成層之表面,藉此保持正或負之電荷狀態。與導電體相鄰之介電體或半導體因導電體之表面電荷狀態之影響而被介電極化,於與具有正電荷之導電體相鄰之側產生負電荷之狀態,於與具有負電荷之導電體相鄰之側產生正電荷之狀態,於該相對電極側產生相反之電荷之狀態。因此,於形成之粒子狀積層物之表面形成有均一且均等之電荷。 圖6(1)、圖6(2)、圖6(3)係模式性表示使用氧化鈦及氧化矽(包含該等之化合物)除外之介電體或半導體、及作為介電體或半導體之氧化鈦或氧化矽(包含該等之化合物),而對基體表面或基體表面層分別賦予正電荷、負電荷、正電荷及負電荷之原理之圖。圖6(1)~(3)中,於氧化鈦及氧化矽(包含該等之化合物)除外之介電體或半導體之粒子CC與作為介電體或半導體之氧化鈦或氧化矽(包含該等之化合物)之粒子BB相鄰之狀態下,於基體表面或基體表面層分別形成有膜或層。於氧化鈦及氧化矽(包含該等之化合物)除外之介電體或半導體中,若形成該物質之電性偶極子迅速與相鄰物質(即,氧化鈦或氧化矽(包含該等之化合物))之經介電極化之表面電荷反應,而使偶極子以與經介電極化之電荷相反之電荷移動,則認為於基體表面或表面層上生成有均一之正或負電荷。圖6(1)、圖6(2)、圖6(3)中,分別表示生成均一之正電荷之態樣、生成均一之負電荷之態樣、生成均一之正電荷及負電荷之態樣。基體表面之造膜方法

關於上述造膜液中之氧化鈦及/或氧化矽(包含氧化鈦及/或氧化矽之化合物)與具有正電荷之物質及/或具有負電荷之物質之複合比,若以固體成分莫耳比表示,則於使用氧化鈦(包含氧化鈦化合物)之情形時,較佳為1:0.01~1:0.3之比率,於使用氧化矽(包含氧化矽之化合物)之情形時,較佳為1:0.03~1:2.7之比率,於使用氧化鈦及氧化矽(包含該等之化合物)之情形時,較佳為1:0.01~1:0.3之比率。 再者,於基體上之造膜較佳為無黏合劑固著,該無黏合劑固著利用的是由作為氧化鈦或氧化矽之自固著化修飾體之過氧基或甲基、或者作為有機矽化合物之矽烷單體或聚矽氧烷聚合物等之H2 O、CO2 之脫離所引起之縮聚反應。 (C)具有正電荷之物質及/或具有負電荷之物質與氧化鈦及/或氧化矽以作為分子等級之複合體之鈣鈦礦型或鈣鈦礦型擬晶粒之形式進行粒子接合而成之膜之造膜方法 圖1(3)係模式性表示(c)之態樣之於基體S1上之造膜剖面之圖。圖中,著色之圓為具有正電荷之物質及/或具有負電荷之物質,未著色之圓表示作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物),由示於外側之圓表示分子等級之粒子於內部取入離子後之結晶構造或擬結晶構造。 於形成氧化鈦或/及氧化矽之Ti分子與O2 分子或O3 分子、或者Si分子與O2 分子或O3 分子於溶液中解離之狀態下,使具有正電荷之物質及/或具有負電荷之物質於分子離子狀態下進行反應,藉由酸性劑、鹼性劑或者電磁波照射等使之固體化,藉此生成複合結晶物。關於進行反應之氧化鈦及/或氧化矽(包含氧化鈦及/或氧化矽之化合物)與具有正電荷之物質及/或具有負電荷之物質之複合比,若以固體成分莫耳比表示,則於使用氧化鈦(包含氧化鈦化合物)之情形時,較佳為1:0.01~1:0.3之比率,於使用氧化矽(包含氧化矽之化合物)之情形時,較佳為1:0.03~1:2.7之比率,於使用氧化鈦及氧化矽(包含該等之化合物)之情形時,較佳為1:0.01~1:0.3之比率。 上述複合結晶物具有通常習知之於內部以離子形式取入複合分子之鈣鈦礦型結晶構造或擬結晶構造,就該複合晶粒而言,Ti或Si作為正電荷發揮功能,O2 作為負電荷發揮功能。因此,於該複合晶粒中,藉由內包之離子,能夠選擇性地呈現兩性、正>負、或負>正之電荷。 以上,使用圖1,對於將於具有正電荷之物質及/或具有負電荷之物質介置作為介電體或半導體之氧化鈦及或氧化矽(包含該等之化合物)而成之膜於基體表面進行造膜之方法之例進行說明。於使用利用圖1之造膜方法時,不論何種基體均能造膜。

另一方面,圖2表示,於基體之表面層中藉由於具有正電荷之物質及/或具有負電荷之物質中介置作為介電體或半導體之氧化鈦與氧化矽(包含該等之化合物),可使電荷不局部化、有效率且穩定地形成於基體表面層中之態樣之例。圖2之(1)、(2)、(3)係模式性表示該等態樣之基板剖面之圖式。圖中,著色之圓為具有正電荷之物質及/或具有負電荷之物質之粒子,未著色之圓表示由作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)形成之粒子。

於圖2(1)及圖2(2)所示之態樣中,並非如圖1(1)所示之具有正電荷之物質及/或具有負電荷之物質之粒子與作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)之粒子鄰接地接合之態樣,而是藉由於包含作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)之基板S2之表面側接合具有正電荷之物質及/或具有負電荷之物質之粒子,或者,藉由於具有正電荷之物質及/或具有負電荷之物質之基板S3之表面側接合氧化鈦及/或氧化矽(包含該等之化合物)之粒子,同樣能夠於基板表面形成均一且均等之電荷。 再者,於圖2之(1)、(2)及(3)中例示出形成於基體之表面層中之粒子之層為1層或2層之例,但為了發揮本發明之功能,期望的是形成於基體之表面層中之粒子之層以複數層形成。 接著,對作為組成本案發明之用於表面電荷形成之粒子狀積層膜之具有正電荷之物質及/或具有負電荷之物質、及作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)較佳為何種物質進行詳細說明。作為介電體或半導體之氧化鈦及 / 或氧化矽

/ 或具有負電荷之物質 關於與作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)複合之具有正電荷之物質及/或具有負電荷之物質,只要為能夠對基體表面賦予正電荷或負電荷者,則可使用任意之具有正電荷或負電荷之物質,較佳為選自由以下之(1)至(6)所組成之群中之至少一種具有正電荷之物質及/或具有負電荷之物質。 (1)陽離子 (2)具有正電荷之導電體、具有正電荷之導電體與介電體之複合體、具有正電荷之導電體與半導體之複合體、包含具有正電荷之2種以上之介電體或/及半導體之複合體之任一具有正電荷之導電體或複合體 (3)陰離子 (4)具有負電荷之導電體、具有負電荷之導電體與介電體之複合體、具有負電荷之導電體與半導體之複合體、包含具有負電荷之2種以上之介電體或/及半導體之複合體之任一具有負電荷之導電體或複合體 (5)具有光觸媒功能之物質 (6)氧化鈦及/或氧化矽(包含氧化鈦及/或氧化矽之化合物)除外之介電體或半導體 作為(1)~(6)之陽離子、陰離子、具有負電荷或正電荷之導電體、作為光觸媒發揮功能之物質、介電體或半導體,雖然不論為有機物質、無機物質、有機物質與無機物質之複合體等物質之種類均可,但為了能夠於基體表面形成穩定之電荷,進而使污染物靜電吸附或者排斥而保護基體,而可形成基於供照射電磁波或熱或光之能量之基體之使用條件下之電荷,就該方面而言,尤佳為使用金屬或金屬以外之一部分無機物質。再者,關於與作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)複合之具有正電荷之物質及/或具有負電荷之物質較佳為主要為金屬,因此,為方便起見,以下,將金屬或金屬以外之一部分無機物質與作為介電體或半導體之氧化鈦(包含氧化鈦之化合物)之複合體稱為金屬摻雜氧化鈦,將金屬或金屬以外之一部分無機物質與作為介電體或半導體之氧化矽(包含氧化矽之化合物)之複合體稱為金屬摻雜氧化矽。 關於與作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)複合之金屬,較佳為選自以金、銀、鉑、銅、錳、鎳、鈷、鐵、鋯、鉿為代表之過渡金屬、以鋅或錫為代表之典型金屬、鹼金屬、鹼土金屬、以鑭或鈰為代表之鑭系元素中之金屬元素或無機元素之至少一種,更佳為使2種金屬元素複合。作為複合之金屬元素,尤佳為銀及銅。 又,關於與作為介電體或半導體之氧化鈦及/或氧化矽(包含該等之化合物)複合之金屬以外之無機物質,較佳為矽。關於金屬摻雜氧化鈦 以下,對作為組成本案發明之用於表面電荷形成之粒子狀積層膜之物質所較佳之金屬(包含金屬以外之一部分無機物質)與作為介電體或半導體之氧化鈦(包含氧化鈦之化合物)之組合加以說明。作為與金屬(包含金屬以外之一部分無機物質)複合之作為介電體或半導體之氧化鈦(包含氧化鈦之化合物),可使用TiO2 、TiO3 、TiO、TiO3 /nH2 O等各種氧化物或過氧化物。尤佳為具有過氧基之過氧化鈦。氧化鈦為非晶型、銳鈦礦型、板鈦礦型、金紅石型之任一種均可,該等亦可混合存在,但較佳為非晶型氧化鈦。其中,使氧化鈦與金屬複合化而成為固體成分之後之氧化鈦呈現銳鈦礦型結晶或銳鈦礦型結晶之前驅物。 在此,對氧化鈦所具有之光觸媒功能與上述金屬摻雜氧化鈦之關係進行說明。其原因在於:若氧化鈦於基體表面發揮光觸媒功能,則根據基體種類之不同,有因光觸媒作用導致基體本身發生分解劣化之虞。氧化鈦中,非晶型氧化鈦及銳鈦礦型結晶前驅物氧化鈦不具有光觸媒功能。另一方面,雖然銳鈦礦型、板鈦礦型及金紅石型氧化鈦具有光觸媒功能,但若使銅、錳、鎳、鈷、鐵或鋅以一定濃度以上與該等氧化鈦複合,則光觸媒功能降低或喪失。再者,非晶型氧化鈦及銳鈦礦型結晶前驅物氧化鈦雖藉由太陽光之加熱等而經時轉化為銳鈦礦型氧化鈦,但若與銅、錳、鎳、鈷、鐵或鋅複合,則銳鈦礦型氧化鈦之光觸媒功能降低。因此,即使為任一型之氧化鈦,摻雜有銅、錳、鎳、鈷、鐵或鋅之鈦氧化物亦可不考慮由光觸媒作用所引起之不良影響。再者,關於摻雜有金、銀、鉑之鈦氧化物,亦包含非晶型氧化鈦轉化為銳鈦礦型氧化鈦之情形在內均具有光觸媒性能,但於摻雜有金、銀、鉑之鈦氧化物中,使正電荷物質以一定濃度以上共存之情形時不顯示光觸媒性能。因此,由於與金、銀、鉑、銅、錳、鎳、鈷、鐵或鋅複合而成之金屬摻雜氧化鈦最終可使光觸媒性能喪失或降低,因此可不考慮由光觸媒作用所產生之不良影響。其中,於使用光觸媒物質作為負電荷物質之情形時,可有效使用藉由光觸媒功能所生成之表面負電荷或負性電荷物。 接著,對上述金屬摻雜氧化鈦之製造方法加以說明。上述金屬摻雜氧化鈦可採用以作為普通二氧化鈦粉末之製造方法之鹽酸法或硫酸法為基礎之製造方法,亦可採用各種液體分散二氧化鈦溶液之製造方法。並且,與氧化鈦複合之金屬或金屬以外之一部分無機物質無論製造階段如何,均能夠與氧化鈦複合化。 以下,一面參照圖3,一面對金屬摻雜氧化鈦之分散液之製造方法之一例加以說明。首先,於將50%四氯化鈦(市售品)經純水稀釋之溶液中,以莫耳比計為1:0.05之比率將於圖3之左側例示之無機物化合物或金屬化合物(具有結晶水之化合物)進行混合。 無機物化合物或金屬化合物可混合複數種。關於四氯化鈦與無機物化合物或金屬化合物之混合比率,以莫耳比計較佳為1:0.01~1:0.3,更佳為1:0.02~1:0.1。向其中滴加25%氨水(市售品)調整至pH7左右,使鈦及無機物或金屬之氫氧化物析出,進行洗淨直至上清液之導電率成為0.9 mS/m以下。於洗淨之氫氧化物中混合濃度為35%之雙氧水,反應數小時後進行超過濾,藉此獲得分散有經複合之無機物質或金屬被修飾之非晶型過氧化鈦之微細粒子之溶液。又,於上述氫氧化物中混合雙氧水使之反應後,加熱並進行超過濾,藉此獲得分散有經複合之無機物質或金屬被修飾之銳鈦礦型過氧化鈦之微細粒子之溶液。 再者,由上述製造方法所得之水性分散液中之過氧化鈦濃度(包含共存之金、銀、鉑、銅、錳、鎳、鈷、鐵、鋅等金屬或無機物之合計量)較佳為0.05~15 wt%,更佳為0.1~5 wt%。 於上述金屬摻雜氧化鈦之製造步驟中,作為用於獲得與氧化鈦(包含其化合物)複合之無機物質或金屬(包含鹼金屬、鹼土金屬)而混合之金、銀、鉑、鎳、鈷、銅、錳、鐵、鋅、鋰、鈉、矽、鉀、鋯、鈰、鉿之化合物之例,可分別列舉以下者。

再者,除參照圖3說明之金屬摻雜氧化鈦分散液之製造方法以外,亦存在較多使無機物質或金屬與氧化鈦複合化之方法,例如可預先分別製作氧化鈦粒子、與所要複合化之無機物質或金屬之粒子,並分別進行混合。於本案發明中,為了製作金屬摻雜氧化鈦,除上述製法以外,亦有多種製造氧化鈦之微細粒子及其分散溶液之方法,可使用其任意一種方法。關於金屬摻雜氧化矽 以下,對作為組成本案發明之用於表面電荷形成之粒子狀積層膜之物質所較佳之金屬(包含金屬以外之一部分無機物質)與作為介電體或半導體之氧化矽(包含氧化矽之化合物)之組合加以說明。關於與金屬(包含金屬以外之一部分無機物質)複合之作為介電體或半導體之氧化矽(包含氧化矽之化合物),可使用SiO2 、SiO3 、SiO、SiO3 /nH2 O等各種氧化物或過氧化物。 作為含有氧化矽之材料,市售有多種製品。例如,作為有機材料與無機材料之結合材料(複合材料),可列舉以下者。 ・賦予複合材料之機械強度之提高或結合性之改良或表面親水性之矽烷偶合劑中,就水解性而言具有甲氧基或乙氧基之水溶性塗佈劑。 ・作為分子內具有有機官能基與烷氧基之低聚物型偶合劑,使各種物質複合化而作為樹脂改質或功能性塗佈劑使用之矽酮低聚物。 ・作為對後述基材之撥水性賦予功能材料使用之具有甲基或長鏈烷基、苯基之烷氧基矽烷或烷氧基氮烷。 ・含有具有有機材料或無機材料之活性氫保護功能之有機矽烷基,藉由控制烷基之反應位置能夠製造有機合成構件之矽烷化劑等。

又,於實施例23之造膜有兩性電荷膜之評價基板中,顯示出實施例20與實施例21之大致中間之碳化污染物之去除性能。 再者,關於各實施例之基板之表面膜之狀態,顯示出即使在碳化聚合物去除作業後亦無擦傷,為能耐受此種環境或作業之硬質之膜。 由此可知,關於利用表面電荷形成之防污技術賦予,無論防污對象物為何種物質,無論造膜基體處於何種使用環境或者使用條件下,均必須考慮電荷來設計對基體表面賦予之電荷之種類。 又,顯示出藉由使用氧化鈦或氧化矽作為介電體及半導體,不僅能夠形成穩定之表面之電荷,而且能夠形成硬質之膜。Hereinafter, embodiments of the present invention will be described with reference to the drawings.summary The inventors of the present invention have found that in order to promote the development of a substrate having a positive charge or a negatively charged substance due to the surface of the substrate or the surface layer of the substrate, the substrate is electrostatically repelled or adsorbed by externally contaminated substances. In the process of protection or environmental improvement, in order to make the charge non-localized, efficiently and stably formed on the surface or surface layer of the substrate, it is important to form a positively charged substance in the surface or surface layer of the substrate. And a particulate layered product in which a negatively charged substance is appropriately interposed between a substance for stably forming a charge or a semiconductor. In addition, the particulate layered product refers to a film or layer formed of a particulate material arranged in a layered manner and formed on the surface or surface layer of the substrate. Further, the inventors of the present invention have found that the dielectric material or semiconductor interposed between the substances for charging the surface of the substrate or the surface layer of the substrate in the particulate layer is a material which is low in cost and easy to use. Titanium oxide and/or cerium oxide (a compound containing titanium oxide and/or cerium oxide) may be selected from the viewpoints of excellent dielectric properties, semiconductor characteristics, and excellent functionality such as a non-adhesive film. In the prior art disclosed by the Applicant, it is disclosed that as a substance for charging a surface of a substrate or a surface layer of a substrate, if it is positively charged, a cation, a positively charged conductor, a positively charged conductor and a composite of a dielectric body and a composite of a positively charged conductor and a semiconductor, and if it is negatively charged, an anion, a negatively charged conductor, a negatively charged conductor and a dielectric composite, A composite of a negatively charged conductor and a semiconductor, and a substance having a photocatalytic function (Patent Document 1 and Patent Document 2). The applicant further found that when two or more kinds of dielectric bodies or semiconductors are combined, they are positively or negatively charged by the type of dielectric or semiconductor used. On the other hand, the inventors of the present invention have newly discovered that titanium oxide and/or cerium oxide (a compound containing titanium oxide and/or cerium oxide) is used as a dielectric interposed between substances which charge the surface of the substrate or the surface layer of the substrate. In the case of a semiconductor, if a dielectric or semiconductor other than titanium oxide and/or antimony oxide (a compound containing titanium oxide and/or antimony oxide) is used, instead of the above-mentioned substance having a positive charge and/or a substance having a negative charge By the kind of the dielectric or semiconductor, the surface of the substrate or the surface layer of the substrate may be positively or negatively charged, and both positive and negative are charged. Therefore, in the following description, although the substance which is positively charged on the surface of the substrate or the surface layer of the substrate is defined as a "positively charged substance", the substance which is negatively charged on the surface of the substrate or the surface layer of the substrate is defined as "having a negative a substance of a charge, but a substance having a positive charge and a substance having a negative charge also includes a dielectric or semiconductor other than "titanium oxide and/or antimony oxide (a compound containing titanium oxide and/or antimony oxide). "." These dielectric bodies or semiconductors have excellent electrostatic polarization and electrostatic induction characteristics, and it is desirable to have a property of changing the charge dipoles in the substances by irradiation of electromagnetic waves or heat or light. In order to more effectively exert a function of electrostatically repelling or adsorbing contaminants from the outside on the surface of the substrate or the surface layer of the substrate, it is desirable to form a particulate laminate on the surface or surface layer of the substrate, and The particulate laminate is regularly taken into the dried and solidified particles to form a uniform and uniform charge. For example, as a preferable example of such a particulate laminate, the following (a) to (c) are exemplified. (a) a surface film or surface layer of a substrate having a positively charged substance and/or a substance having a negative charge and a titanium oxide and/or cerium oxide as a dielectric or semiconductor, respectively, by particle bonding of a single particle (b) a substrate having a positive charge by a particle surface obtained by particle bonding of colloidal particles obtained by coating a colloidal particle having a positively charged substance and/or a negatively charged substance in titanium oxide or cerium oxide and/or Or a surface film or a surface layer formed by particle bonding of a substance having a negative charge and titanium oxide and/or cerium oxide in the form of a perovskite or perovskite type crystallite as a composite of molecular grades. The particle size of the particulate laminate on the surface of the substrate or the surface layer is preferably from 0.1 nm to 100 nm. Further, the layer thickness of the laminate is not particularly limited, but is preferably in the range of 10 nm to 1 μm, more preferably in the range of 10 nm to 100 nm.About the principle of charge formation Hereinafter, the positive or negative charge or the negative charge is applied to the surface of the substrate or the surface layer of the substrate by using the particulate laminate formed on the surface of the substrate or the surface of the substrate as described in the above (a), as shown in FIG. 5 and FIG. The principle of charge formation of positive and negative charges will be described. 5(1), 5(2), and 5(3) schematically show the use of a substance having a positive charge and/or a substance having a negative charge and a titanium oxide or a cerium oxide as a dielectric or semiconductor (including These compounds) are diagrams that give the principle of positive, negative, positive and negative charges on the surface of the substrate or on the surface layer of the substrate. In Fig. 5 (1), on the surface of the substrate or the surface of the substrate, the particles AP of the positively charged conductor are adjacent to the particles BB of the dielectric or semiconductor titanium oxide or cerium oxide (including the compound).

In this respect, it is particularly preferable to use a metal or a metal. A part of inorganic substances. Further, it is preferable that a substance having a positive charge and a substance having a negative charge which are complexed with titanium oxide and/or cerium oxide (including the compound) as a dielectric or semiconductor are mainly metals, and therefore, For the sake of convenience, a composite of a part of an inorganic substance other than a metal or a metal and a titanium oxide (a compound containing titanium oxide) as a dielectric or a semiconductor is hereinafter referred to as a metal-doped titanium oxide, and a metal or a metal A composite of a part of an inorganic substance and a cerium oxide (a compound containing cerium oxide) as a dielectric or a semiconductor is referred to as a metal-doped cerium oxide.

As a composite metal element, silver and copper are particularly preferred. Further, the inorganic substance other than the metal which is a composite of titanium oxide and/or cerium oxide (including these compounds) as a dielectric or semiconductor is preferably ruthenium.About metal doped titanium oxide In the following, a metal (including a part of an inorganic substance other than a metal) and a titanium oxide (a compound containing titanium oxide) as a dielectric or semiconductor are preferable as the material constituting the particulate-shaped laminated film for surface charge formation of the present invention. The combination is explained. As a titanium oxide (a compound containing titanium oxide) which is a dielectric or a semiconductor compounded with a metal (a part of an inorganic substance other than a metal), TiO can be used.2 TiO3 , TiO, TiO3 /nH2 Various oxides or peroxides such as O. It is especially preferred to be a titanium peroxide having a peroxy group. The titanium oxide may be any of an amorphous type, an anatase type, a brookite type, and a rutile type, and these may be mixed, but are preferably amorphous titanium oxide. Among them, the titanium oxide obtained by combining titanium oxide with a metal to form a solid component exhibits an anatase crystal or an anatase crystal precursor. Here, the relationship between the photocatalytic function of the titanium oxide and the metal-doped titanium oxide described above will be described. The reason for this is that if the titanium oxide functions as a photocatalyst on the surface of the substrate, depending on the type of the substrate, the substrate itself may be decomposed and deteriorated due to the photocatalytic action. Among the titanium oxide, the amorphous titanium oxide and the anatase type crystalline precursor titanium oxide do not have a photocatalytic function. On the other hand, although the anatase type, brookite type, and rutile type titanium oxide have a photocatalytic function, if copper, manganese, nickel, cobalt, iron, or zinc is combined with the titanium oxide at a certain concentration or more, The photocatalytic function is reduced or lost. Further, the amorphous titanium oxide and the anatase type crystal precursor titanium oxide are converted into anatase-type titanium oxide by time by heating by sunlight or the like, but if combined with copper, manganese, nickel, cobalt, iron Or zinc composite, the photocatalytic function of anatase titanium oxide is reduced. Therefore, even if it is any type of titanium oxide, the titanium oxide doped with copper, manganese, nickel, cobalt, iron or zinc may not be considered to have an adverse effect caused by the photocatalytic action. Furthermore, the titanium oxide doped with gold, silver or platinum also contains photocatalytic properties including amorphous titanium oxide converted to anatase titanium oxide, but is doped with gold, silver, In the titanium oxide of platinum, when a positively-charged substance coexists at a certain concentration or more, the photocatalytic performance is not exhibited. Therefore, since the metal-doped titanium oxide compounded with gold, silver, platinum, copper, manganese, nickel, cobalt, iron or zinc can eventually lose or reduce the photocatalytic performance, the adverse effects caused by the photocatalytic action can be ignored. . Among them, when a photocatalytic substance is used as a negatively-charged substance, a surface negative charge or a negative charge generated by a photocatalytic function can be effectively used. Next, a method of producing the above-described metal-doped titanium oxide will be described. The metal-doped titanium oxide may be a production method based on a hydrochloric acid method or a sulfuric acid method as a method for producing a conventional titanium oxide powder, or a method for producing various liquid-dispersed titanium oxide solutions. Further, a part of the inorganic substance other than the metal or the metal compounded with the titanium oxide can be combined with the titanium oxide regardless of the production stage.

Evaluation 2 Sand dust adsorption and antifouling evaluations of Examples 11 to 19 and Comparative Example 2 were carried out using three types of dust in the Kanto loam layer, Dubai desert sand dust in the Middle East, and volcanic ash in the Kyushu area. The surface dust of the Kanto loam, the dust of the desert in the Middle East, and the volcanic ash of the Kyushu area were dropped to the surface of the substrates of Examples 11 to 19 and Comparative Example 2, respectively, and used as evaluation substrates, and the evaluation substrates were raised. The gloss was measured by gently rubbing twice on the table and using a gloss meter IG-331 (manufactured by Horiba, Ltd.). Then, the difference in gloss between the substrates of the respective examples and the comparative examples measured before the addition of dust or volcanic ash was determined, thereby evaluating the antifouling against the dust adsorption according to the diffuse reflectance of the light due to the adhesion residual. The results of the evaluation and the evaluation results (average measured at three places) are shown in Table 3 below (value: gloss before powder evaluation - gloss after powder evaluation). [table 3] <Result 2> Table 3 reveals the following results. In the case of using the Kanto loam powder, Examples 11 to 13 which are film-forming substrates of positive charge surface characteristics, and glosses before and after evaluation of Examples 17 to 19 which are films of amphoteric charge surface characteristics were exhibited. The change is low. For the Kanto loam powder, the positive or gender-charged surface has antifouling function. The antifouling function is also the same when using Dubai desert dust powder. In the case of using the volcanic ash powder in the Kyushu region, the changes in gloss before and after the evaluation of Examples 14 to 16 which are film-forming substrates having negative charge surface characteristics were low, and for the volcanic ash powder, the negative-charged surface was stain-resistant. Features. On the other hand, the surface of the non-film-forming blue float glass of Comparative Example 2 showed a glossiness value based on the adhesion of the three kinds of powders. Example 20 On the surface of a common soda lime float glass (100 mm × 100 mm thick 3 mm) substrate, using a sponge extrusion method at 10 g/m2 The ratio of the dispersion of Reference Example 1 was applied and heated at 300 ° C for 10 minutes to prepare Example 20. Example 21 Example 21 was produced by the same production method as in Example 20, using the dispersion liquid of Reference Example 4. Example 22 Example 22 was produced by the same production method as in Example 20, using the dispersion liquid of Reference Example 5. Example 23 Example 23 was produced by the same production method as in Example 20, using the dispersion liquid of Reference Example 7. Comparative Example 3 A non-film-forming person on a common soda lime float glass (100 mm × 100 mm thick 3 mm) substrate was designated as Comparative Example 3. Evaluation 3 On the upper surface of the substrate of Examples 20 to 23 and the substrate of Comparative Example 3, a liquid of a stirred egg liquid and a commercially available olive oil were applied at a width of about 20 mm and a length of about 60 mm at 300 ° C. After heating for 30 minutes, each of the carbonized polymers was fixed to prepare each evaluation substrate, and the method of wiping the surface of each of the evaluation substrates by water-absorbent surface paper and the method of wiping the soft side of the kitchen sponge to wipe the surface of each evaluation substrate were performed. The ease of removal obtained by electrostatic repulsion of the carbides was evaluated. Further, regarding the state of the surface film formed on the substrate of each of the examples, the surface film after the removal of the carbonized polymer was visually evaluated for the presence or absence of scratches. The results are shown in Table 4 below. [Table 4] <Result 3> Table 4 shows the removal performance of the viscous contaminant obtained by electrostatic repelling when the substrate was in a heated environment or use condition. As is apparent from Table 4, in Comparative Example 21 and Example 22, the evaluation of the substrate having a negative charge film before heating was carried out without adsorption of carbonized contaminants, and the removal performance was excellent. On the other hand, in the evaluation substrate of Example 20 in which a positively-charged film was formed before heating and the non-film-formed substrate of Comparative Example 3, it was revealed that the fixed carbonized contaminant could not be removed. Further, in the evaluation substrate of the film having the amphoteric charge film of Example 23, the removal performance of the carbonized contaminant substantially in the middle of Example 20 and Example 21 was exhibited. Further, the state of the surface film of the substrate of each of the examples showed a film which was hard to withstand such an environment or work even if it was not scratched even after the carbonized polymer removal operation. Therefore, it is understood that the antifouling technique by surface charge formation imparts charge to the surface of the substrate regardless of the environment in which the film-forming substrate is used or the conditions of use, regardless of the substance to be used for the object to be treated. The type. Further, it has been shown that by using titanium oxide or cerium oxide as a dielectric and a semiconductor, it is possible to form not only a stable surface charge but also a hard film.
