CoSo 0992017828-0 201135685 [0019] 所述奈米碳管層狀結構包括至少一層奈米碳管膜。當奈 米碳管層狀結構包括至少兩層奈米碳管膜時，該至少兩 層奈米碳管膜層疊設置或並排設置。所述奈米碳管膜包 括均勻分佈的奈米碳管，奈米碳管之間通過凡德瓦爾力 緊密結合。該奈米碳管膜中的奈米碳管為無序或有序排 列。這裏的無序排列指奈米碳管的排列方向無規律，這 裏的有序排列指至少多數奈米碳管的排列方向具有一定 規律。具體地，當奈米碳管膜包括無序排列的奈米碳管 時，奈米碳管相互纏繞或者各向同性排列；當奈米碳管 層狀結構包括有序排列的奈米碳管時，奈米碳管沿一個 方向或者複數個方向擇優取向排列。本實施例中，優選 地，所述奈米碳管層狀結構包括複數個層疊設置的奈米 碳管膜，且該奈米碳管層狀結構的厚度優選為0. 5奈米〜1 毫米。優選地，該奈米碳管層狀結構的厚度為100奈米 〜0. 1毫米。可以理解，當奈米碳管層狀結構的透明度與 奈米碳管層狀結構的厚度有關，當奈米碳管層狀結構的 厚度越小時，該奈米碳管層狀結構的透光度越好。所述 奈米碳管層狀結構的單位面積熱容小於2x1 0_4焦耳每平 方厘米開爾文。優選地，所述奈米碳管層狀結構的單位 面積·熱容可以小於等於1. 7x1 (Γ6焦耳每平方厘米開爾文

[0020] 〇 請參閱圖3，所述奈米碳管膜可以為一奈米碳管拉膜。該 奈米碳管拉膜為從奈米碳管陣列中直接拉取獲得的一種 奈米碳管膜。每一奈米碳管膜是由若干奈米碳管組成的 自支撐結構。所述若干奈米碳管為基本沿同一方向擇優 取向排列。所述擇優取向是指在奈米碳管膜中大多數奈 米碳管的整體延伸方向基本朝同一方向。而且，所述大 多數奈米碳管的整體延伸方向基本平行於奈米碳管膜的 表面。進一步地，所述奈米碳管膜中多數奈米碳管是通 過凡德瓦爾力首尾相連。具體地，所述奈米碳管膜中基 本朝同一方向延伸的大多數奈米碳管中每一奈米碳管與 在延伸方向上相鄰的奈米碳管通過凡德瓦爾力首尾相連 。當然，所述奈米碳管膜中存在少數隨機排列的奈米碳 管，這些奈米碳管不會對奈米碳管膜中大多數奈米碳管 的整體取向排列構成明顯影響。所述自支撐為奈米碳管 膜不需要大面積的載體支撐，而只要相對兩邊提供支撐 力即能整體上懸空而保持自身膜狀狀態，即將該奈米碳 〇 管膜置於（或固定於）間隔一固定距離設置的兩個支撐 體上時，位於兩個支撐體之間的奈米碳管膜能夠懸空保 持自身膜狀狀態。所述自支撐主要通過奈米碳管膜中存 在連續的通過凡德瓦爾力首尾相連延伸排列的·奈米碳管 而實現。 - [0021] 具體地，所述奈米碳管膜中基本朝同一方向延伸的多數 奈米碳管，並非絕對的直線狀，可以適當的彎曲；或者 並非完全按照延伸方向上排列，可以適當的偏離延伸方 向。因此，不能排除奈米碳管膜的基本朝同一方向延伸 099110101 表單編號A0101 第11頁/共39頁 0992017828-0 201135685 的多數奈米碳管中並列的奈米碳管之間可能存在部分接 觸。 [0022] 所述奈米碳管拉膜的厚度為0. 5奈米〜100微米，寬度與拉 取該奈米碳管拉膜的奈米碳管陣列的尺寸有關，長度不 限。 [0023] 當所述奈米碳管層狀結構採用奈米碳管拉膜時，其可以 包括層疊設置的多層奈米碳管拉膜，且相鄰兩層奈米碳 管拉膜中的奈米碳管之間沿各層中奈米碳管的轴向形成 一交叉角度α，α大於等於0度小於等於90度（0 ° α 〇 90°)。所述複數個奈米碳管拉膜之間或一個奈米碳管拉 膜之中的相鄰的奈米碳管之間具有間隙，從而在奈米碳 管結構中形成複數個微孔，微孔的孔徑約小於10微米。 [0024] 請參見圖4，所述奈米碳管膜還可以為一奈米碳管絮化膜 。所述奈米碳管絮化膜為通過一絮化方法形成的奈米碳 管膜。該奈米碳管絮化膜包括相互纏繞且均勻分佈的奈 米碳管。所述奈米碳管之間通過凡德瓦爾力相互吸引、 I ) 纏繞，形成網路狀結構。所述奈米碳管絮化膜各向同性 > 。所述奈米碳管絮化膜的長度和寬度不限。由於在奈米 碳管絮化膜中，奈米碳管相互纏繞，因此該奈米碳管絮 化膜具有很好的柔韌性，且為一自支撐結構，可以彎曲 折疊成任意形狀而不破裂。所述奈米碳管絮化膜的面積 _ 及厚度均不限，厚度為1微米~1毫米。 [0025] 所述奈米碳管膜還可以為通過碾壓一奈米碳管陣列形成 的奈米碳管碾壓膜。該奈米碳管碾壓膜包括均勻分佈的 099110101 表單編號Α0101 第12頁/共39頁 0992017828-0 201135685 奈米碳管，奈米碳管沿同一方向或不同方向擇優取向排 列。奈米碳管也可以是各向同性的。所述奈米碳管碾壓 膜中的奈米碳管相互部分交疊，並通過凡德瓦爾力相互 吸引，緊密結合。所述奈米碳管碾壓膜中的奈米碳管與 形成奈米碳管陣列的生長基底的表面形成一夾角沒，其 中，yS大於等於0度且小於等於15度（0 β 15°)。依 據碾壓的方式不同，該奈米碳管碾壓膜中的奈米碳管具 有不同的排列形式。請參閱圖5，當沿同一方向碾壓時， 奈米碳管沿一固定方向擇優取向排列。可以理解，當沿 不同方向碾壓時，奈米碳管可沿複數個方向擇優取向排 列。該奈米碳管碾壓膜厚度不限，優選為為1微米~1毫米 。該奈米碳管碾壓膜的面積不限，由碾壓出膜的奈米碳 管陣列的大小決定。當奈米碳管陣列的尺寸較大時，可 以碾壓制得較大面積的奈米碳管碾壓膜。 ❹ [0026] 採用奈米碳管層狀結構作為第一加熱元件106或第二加熱 元件108時具有以下優點：其一，由於#来碳管層狀結構 由奈米碳管構成，奈米碳管不f.g化，因此第一加熱 元件106或第二加熱元件108的壽命較長；其二，所述奈 米碳管狀結構的密度較小，因此該熱致顯示元件100的品 質較輕；其三，奈米碳管層狀結構具有較好的柔韌性， 可以任意彎折而不被破壞，因此，該熱致顯示元件100可 以做成柔性結構；其四，由於奈米礙管的熱容較小，所 以由該奈米碳管層狀結構構成的加熱元件具有較快的熱 回應速度，可用於對物體進行快速加熱，所以該熱致顯 示元件10 0反應速度較快，可以快速的顯示和擦拭。 099110101 表單編號A0101 第13頁/共39頁 0992017828-0 201135685 闕料至少兩個第一電極114用於連接第—加熱元件ι〇6和

When the carbon nanotube layered structure comprises at least two layers of carbon nanotube film, the at least two layers of carbon nanotube film are stacked or arranged side by side. The carbon nanotube membrane comprises uniformly distributed carbon nanotubes, and the carbon nanotubes are tightly bonded by van der Waals force. The carbon nanotubes in the carbon nanotube membrane are disordered or ordered. The disordered arrangement here means that the arrangement direction of the carbon nanotubes is irregular, and the orderly arrangement here means that at least most of the arrangement of the carbon nanotubes has a certain regularity. Specifically, when the carbon nanotube film comprises a disordered arrangement of carbon nanotubes, the carbon nanotubes are intertwined or isotropically aligned; when the carbon nanotube layered structure comprises an ordered arrangement of carbon nanotubes The carbon nanotubes are arranged in a preferred orientation in one direction or in a plurality of directions. 5纳米〜1毫米 The thickness of the carbon nanotube layered structure is preferably 0.5 nm to 1 mm. The thickness of the carbon nanotube layered structure is preferably 0.5 nm to 1 mm. . 01毫米。 The thickness of the carbon nanotube layered structure is 100 nm ~ 0. 1 mm. It can be understood that when the transparency of the layer structure of the carbon nanotube is related to the thickness of the layer structure of the carbon nanotube, the transmittance of the layer structure of the carbon nanotube is smaller when the thickness of the layer structure of the carbon nanotube is smaller. The better. The carbon nanotube layered structure has a heat capacity per unit area of less than 2 x 10 0 4 joules per square centimeter Kelvin. Preferably, the carbon nanotube layered structure has a unit area and heat capacity of less than or equal to 1. 7x1 (Γ6 joules per square centimeter Kelvin. Since the heat capacity of the carbon nanotubes is small, the carbon nanotubes are The layered structure of the heating element has a faster thermal response speed and can be used to rapidly heat the object. It can be understood that the thermal response speed of the carbon nanotube layered structure is related to its thickness. In the case of the same area, the nanometer The greater the thickness of the carbon tube layered structure, the slower the heat response speed; conversely, the smaller the thickness of the carbon nanotube layered structure, the faster the heat response speed. 099110101 Form No. A0101 Page 10 / Total 39 Page 0992017828-0 201135685 [0020] Referring to FIG. 3, the carbon nanotube film may be a carbon nanotube film. The carbon nanotube film is a kind of nanometer obtained by directly pulling from a carbon nanotube array. Carbon tube membrane. Each nano carbon tube membrane is a self-supporting structure composed of a number of carbon nanotubes. The several carbon nanotubes are arranged in a preferred orientation along substantially the same direction. The preferred orientation refers to nanocarbon. Most of the nanotubes in the membrane The overall extension direction of the tubes is substantially in the same direction. Moreover, the overall extension direction of the majority of the carbon nanotubes is substantially parallel to the surface of the carbon nanotube film. Further, most of the carbon nanotubes in the carbon nanotube film The tubes are connected end to end by van der Waals force. Specifically, each of the carbon nanotubes in the majority of the carbon nanotube membranes extending in the same direction is adjacent to the nanometer in the extending direction. The carbon tubes are connected end to end by van der Valli. Of course, there are a few randomly arranged carbon nanotubes in the carbon nanotube membrane, and these carbon nanotubes do not affect most of the carbon nanotubes in the carbon nanotube membrane. The overall orientation arrangement has a significant influence. The self-supporting carbon nanotube film does not require a large area of carrier support, and as long as the supporting force is provided on both sides, it can be suspended as a whole to maintain its own film state, that is, the nano carbon When the fistula membrane is placed (or fixed) on two supports arranged at a fixed distance, the carbon nanotube membrane located between the two supports can be suspended to maintain its own membranous state. The self-supporting mainly passes In the carbon nanotube film, there is a continuous carbon nanotube arranged by the end of the van der Waals force. - [0021] Specifically, the majority of the carbon nanotube film extends in the same direction. The carbon nanotubes are not absolutely linear and can be bent properly; or they are not completely aligned in the direction of extension, and can be appropriately deviated from the direction of extension. Therefore, it is not excluded that the carbon nanotube film extends substantially in the same direction. 099110101 Form No. A0101 5米米的厚度。 The thickness of the nano carbon tube is 0. 5 nm. The thickness of the nano carbon tube is 0. 5 nm ~100 microns, the width is related to the size of the carbon nanotube array that pulls the carbon nanotube film, and the length is not limited. [0023] When the carbon nanotube layered structure is formed by using a carbon nanotube film, it may include a laminated multilayer carbon nanotube film, and the adjacent two layers of carbon nanotubes are pulled in the film. The carbon nanotubes form an intersection angle α along the axial direction of the carbon nanotubes in each layer, and α is greater than or equal to 0 degrees and less than or equal to 90 degrees (0 ° α 〇 90°). a gap is formed between the plurality of carbon nanotube films or between adjacent carbon nanotubes in a carbon nanotube film, thereby forming a plurality of micropores in the carbon nanotube structure.

The carbon nanotubes are attracted to each other by the van der Waals force, and I) are entangled to form a network structure. The carbon nanotube flocculation membrane is isotropic >. The length and width of the carbon nanotube film are not limited. Since the carbon nanotubes are intertwined in the carbon nanotube flocculation membrane, the carbon nanotube flocculation membrane has good flexibility and is a self-supporting structure, which can be bent and folded into any shape without breaking. . The carbon nanotube film of the carbon nanotubes has an area _ and a thickness of not less than 1 micrometer to 1 mm. [0025] The carbon nanotube film may also be a carbon nanotube rolled film formed by rolling an array of carbon nanotubes.

The carbon nanotubes can also be isotropic. The carbon nanotubes in the carbon nanotube rolled film partially overlap each other and are attracted to each other by the van der Waals force, and are tightly bonded. The carbon nanotubes in the carbon nanotube rolled film form an angle with the surface of the growth substrate forming the carbon nanotube array, wherein yS is greater than or equal to 0 degrees and less than or equal to 15 degrees (0 β 15°) . The carbon nanotubes in the carbon nanotube rolled film have different arrangements depending on the manner of rolling. Referring to Figure 5, when rolled in the same direction, the carbon nanotubes are arranged in a preferred orientation along a fixed orientation. It will be appreciated that when compacted in different directions, the carbon nanotubes may be arranged in a preferred orientation along a plurality of directions. The thickness of the carbon nanotube rolled film is not limited, and is preferably 1 μm to 1 mm. The area of the carbon nanotube rolled film is not limited, and is determined by the size of the carbon nanotube array which is rolled out of the film. When the size of the carbon nanotube array is large, a large area of the carbon nanotube rolled film can be crushed. [0026] When the carbon nanotube layered structure is used as the first heating element 106 or the second heating element 108, the following advantages are obtained: First, since the carbon nanotube layered structure is composed of a carbon nanotube, the carbon nanotube Not fg, so the life of the first heating element 106 or the second heating element 108 is longer; secondly, the density of the nano carbon tubular structure is small, so the quality of the thermally induced display element 100 is light; The carbon nanotube layered structure has better flexibility and can be bent without being damaged. Therefore, the thermally induced display element 100 can be made into a flexible structure; and fourth, because the heat capacity of the nano tube is obstructed Small, so the heating element composed of the carbon nanotube layer structure has a faster thermal response speed and can be used for rapid heating of the object, so the thermotropic display element 10 0 has a faster reaction speed and can be quickly displayed and wipe. 099110101 Form No. A0101 Page 13 / Total 39 Page 0992017828-0 201135685 Feeding at least two first electrodes 114 for connecting the first heating element ι 6 and the external π circuit 'to pass an external circuit through the at least two first electrodes (1) An electric current is supplied to the first heating element 106, so that the first heating element 106 generates Joule heat' to perform heating.
