Description
本發明係有關於一種具超疏水表面之物品及其製備方法，特別是一種具有高疏水性、所需的防潑水性以及良好的清洗耐受性的具超疏水表面之物品以及具超疏水表面之物品的製備方法。The present invention relates to an article with a superhydrophobic surface and a preparation method thereof, particularly an article with a superhydrophobic surface and a superhydrophobic surface with high hydrophobicity, required water repellency and good cleaning tolerance The method of preparation of the article.
因超疏水物品的獨特性質，例如濕潤性、自清潔性以及抗沾粘性等特性，近年來已有許多研究及商品對於超疏水物品的關心日益增加。已知固體表面的濕潤現象可由表面的幾何結構以及材料的化學組成所控制。近來，潤濕性研究的範圍已經擴展到製造具有其他功能的超疏水表面，以應用於先進材料中。在這方面，已經通過新方法製備了一些具有多功能的超疏水表面物品。例如，以包含超微米蠟或聚四氟乙烯顆粒的不同氰基丙烯酸乙酯奈米複合物殼功能化纖維素纖維以增加疏水性，藉由MnFe 2O 4奈米粒子以增加磁性，藉由量子點CdSe/ZnS以發光或藉由奈米銀粒子(AgNPs)得到抗菌作用；藉由在物品表面上塗覆Pt、Au或AgNPs來得到良好的自淨和抗菌物品。然而，前述方法具有塗覆材料昂貴、製程複雜例如還需要等離子處理或射頻(RF)濺射等缺點。 Due to the unique properties of superhydrophobic articles, such as wetting, self-cleaning, and anti-stick properties, there have been many studies and commercial interest in superhydrophobic articles in recent years. Wetting of solid surfaces is known to be governed by the geometry of the surface as well as the chemical composition of the material. Recently, the scope of wettability research has been extended to fabricate superhydrophobic surfaces with other functionalities for application in advanced materials. In this regard, some superhydrophobic surface objects with multifunctionality have been prepared by new methods. For example, cellulose fibers were functionalized with different ethyl cyanoacrylate nanocomposite shells containing ultra - micron wax or Teflon particles to increase hydrophobicity, by MnFe2O4 nanoparticles to increase magnetism, by Quantum dots CdSe/ZnS can emit light or obtain antibacterial effect by nano silver particles (AgNPs); good self-cleaning and antibacterial articles can be obtained by coating Pt, Au or AgNPs on the surface of articles. However, the aforementioned methods have disadvantages such as expensive coating materials and complicated manufacturing processes such as plasma treatment or radio frequency (RF) sputtering.
在現有技術中，已知可利用層狀雙氫氧化物(layered double hydroxide, LDH)在例如織物或布料的物品表面上以增加疏水性。層狀雙氫氧化物可藉由例如水解，共沉澱，重構，陰離子交換反應，尿素法，溶膠-凝膠技術，微波，超聲波或水熱程序而形成。然而，前述方法具有需要高反應溫度或壓力的缺點，不僅會降低或削弱布料結構，且亦對環境不友善。此外，習知的在表面具有層狀雙氫氧化物因其清洗耐受性不佳，物品的疏水性在清洗後會下降。因此，現有技術中的表面具有層狀雙氫氧化物的物品並不被建議使用在耐用布料的應用中。In the prior art, it is known to use layered double hydroxide (LDH) on the surface of an item such as fabric or cloth to increase hydrophobicity. Layered double hydroxides can be formed by, for example, hydrolysis, coprecipitation, reconstitution, anion exchange reactions, urea processes, sol-gel techniques, microwave, ultrasonic or hydrothermal procedures. However, the aforementioned method has the disadvantage of requiring high reaction temperature or pressure, which not only reduces or weakens the fabric structure, but is also environmentally unfriendly. In addition, the conventional layered double hydroxide on the surface has poor cleaning resistance, and the hydrophobicity of the article will decrease after cleaning. Therefore, prior art articles with layered double hydroxides on the surface are not recommended for use in durable fabric applications.
因此，本發明之一目的係提供一種具超疏水表面之物品以及一種具超疏水表面之物品的製備方法。Therefore, an object of the present invention is to provide an article with a superhydrophobic surface and a preparation method of the article with a superhydrophobic surface.

防潑水性測試Water repellency test
防潑水性係根據AATCC 22-2005標準評估。首先從實施例及比較例之布料中各剪出三塊大小為180.0×180.0 mm作為試樣，再將試樣與直徑為150±5 mm之金屬環套合並使試樣朝向水的噴灑方向，試樣與金屬噴嘴的距離為150±2 mm。接著，以噴嘴將250mL的去離子水向試樣噴灑，噴灑時間為20至30秒。最後，在敲打試樣後，將試樣上沾濕形成的圖案與標準圖片對比。Water repellency is evaluated according to AATCC 22-2005. First, cut out three pieces of 180.0 × 180.0 mm from the cloth of the embodiment and the comparative example as samples, and then wrap the samples with a metal ring with a diameter of 150 ± 5 mm and make the samples face the spraying direction of water. The distance between the sample and the metal nozzle is 150 ± 2 mm. Next, 250 mL of deionized water was sprayed on the sample with a nozzle for 20 to 30 seconds. Finally, after tapping the sample, the pattern formed by the wetting on the sample is compared with the standard picture.
根據潑水測試標準評級，ISO 5表示表面沒有濕潤痕跡; ISO 4 表示表面稍有濕潤痕跡; ISO 3表示表面噴嘴噴灑點有濕潤痕跡; ISO 2 表面大部分為濕潤狀; ISO 1表示表面整個為濕潤狀; ISO 0表示試樣完全被浸溼。According to the water splash test standard rating, ISO 5 means that the surface has no traces of wetness; ISO 4 means that the surface is slightly wet; ISO 3 means that there are traces of wetness at the spray point of the surface nozzle; ISO 2 means that the surface is mostly wet; ISO 1 means that the surface is completely wet state; ISO 0 indicates that the specimen is completely wet.
清洗耐受性測試Cleaning tolerance test
依照AATCC TM 135標準將實施例及比較例之具疏水錶面之布料清洗十次後，再依前述的防潑水性測試方法測量清洗後的防潑水性。The fabrics with hydrophobic surfaces of the Examples and Comparative Examples were washed ten times according to the AATCC TM 135 standard, and then the water repellency after washing was measured according to the aforementioned water repellency test method.
表1：實施例與比較例之測試結果
於表1所列之測試結果可見，實施例1至實施例5之水接觸角皆為135°。故，相較於比較例1，本發明實施例1至實施例5之布料皆具有更優異的疏水性。此外，實施例1至實施例5之布料在經過清洗後，防潑水性皆仍可維持在ISO 5，可見清洗後仍可維持良好的疏水性及防潑水性。而比較例1及比較例2之布料則因清洗耐受性過低而無法作為耐用布料使用。From the test results listed in Table 1, it can be seen that the water contact angles of Examples 1 to 5 are all 135°. Therefore, compared with Comparative Example 1, the fabrics of Examples 1 to 5 of the present invention all have better hydrophobicity. In addition, the water repellency of the fabrics of Examples 1 to 5 can still be maintained at ISO 5 after cleaning, which shows that good hydrophobicity and water repellency can still be maintained after cleaning. On the other hand, the cloths of Comparative Example 1 and Comparative Example 2 could not be used as durable cloths because the cleaning resistance was too low.
