Description
技术领域 本发明属于碳纳米管膜的制造方法，特别是在软基底上制造定向碳纳米管膜的制造方法。Technical field The present invention belongs to the manufacturing method of carbon nanotube film, especially the manufacturing method of manufacturing aligned carbon nanotube film on soft substrate.
背景技术 现有的碳纳米管膜有两种形式。一种是在石英、硅基底(即所谓的硬基底)上直接沉积出具有定向排列的碳纳米管的膜。这些膜可以用来制造平板显示器、X光发生管、白织灯等电器元件的发射电子元件；也可以是直接沉积在宝石基底上，作为半导体元器件的散热膜。另一种是与聚合物复合成复合薄膜，这种复合薄膜中的碳纳米管的位向是随机分布，采用切片方式，可以使一部分碳纳米管从膜中露出。这种复合膜可以作为平板显示器，导热膜，吸收微波用薄膜。从利用碳纳米管的单向优秀性能方面，第一种膜好，但是第一种方法制造的碳纳米管膜是硬的衬底，从而限制了它的应用范围。第二种膜虽然应用方便，但是由于碳纳米管的位向是随机分布，同时在复合材料混制过程中，碳纳米管的均匀分散不均匀，将会大大地影响碳纳米管的使用性能。如现在的碳纳米管复合材料用作导热膜，效果就差。Background Art There are two types of existing carbon nanotube films. One is to directly deposit a film with aligned carbon nanotubes on a quartz or silicon substrate (the so-called hard substrate). These films can be used to manufacture emissive electronic components of electrical components such as flat panel displays, X-ray generating tubes, and white woven lamps; they can also be directly deposited on gemstone substrates as heat dissipation films for semiconductor components. The other is to combine with polymers to form a composite film. The orientation of the carbon nanotubes in this composite film is randomly distributed, and a part of the carbon nanotubes can be exposed from the film by slicing. This composite film can be used as a flat panel display, a heat conduction film, and a film for absorbing microwaves. From the aspect of using the excellent unidirectional performance of carbon nanotubes, the first film is good, but the carbon nanotube film produced by the first method is a hard substrate, which limits its application range. Although the second film is convenient to use, because the orientation of carbon nanotubes is randomly distributed, and at the same time, the uniform dispersion of carbon nanotubes in the process of composite material mixing will greatly affect the performance of carbon nanotubes. If the current carbon nanotube composite material is used as a heat-conducting film, the effect is poor.
发明内容 本发明的目的是提供一种具有上述两种膜特点的碳纳米管膜的制造工艺，在各种条件下都能最大限度地利用碳纳米管的轴向优秀性能。SUMMARY OF THE INVENTION The purpose of the present invention is to provide a carbon nanotube film manufacturing process with the characteristics of the above two films, which can make maximum use of the excellent axial performance of carbon nanotubes under various conditions.
本发明的制造碳纳米管膜的技术路线描述如下：The technical route of manufacturing carbon nanotube film of the present invention is described as follows:
1、利用现有的生长多层定向碳纳米管的工艺，在石英或硅基底上沉积碳纳米管膜；2、在800号金相砂纸上研磨平碳纳米管膜；3、在需要生成碳纳米管膜的软基底上涂覆一层胶粘剂，再将此基底粘在研磨好的碳纳米管膜的表面；4、从碳纳米管膜上揭下此基底，形成软基底的定向碳纳米管膜。其中所述的软基底是金属膜、塑料或者纸基底。1. Utilize the existing process of growing multilayer oriented carbon nanotubes to deposit carbon nanotube films on quartz or silicon substrates; 2. Grind flat carbon nanotube films on No. 800 metallographic sandpaper; 3. Generate carbon nanotube films when needed Coating a layer of adhesive on the soft substrate of the nanotube film, and then sticking the substrate on the surface of the ground carbon nanotube film; 4, peeling off the substrate from the carbon nanotube film to form aligned carbon nanotubes on the soft substrate membrane. The soft substrate described therein is a metal film, plastic or paper substrate.
经过上述4个步骤，在石英或硅基底上形成的定向碳纳米管膜就被转移到软基底上，从而制作成了软基底定向碳纳米管膜。重复上述第3和第4步骤，就可以把沉积在石英或硅基底上的多层碳纳米管膜十分方便地逐层转移到软基底上，制作成多片软基底定向碳纳米管膜。After the above four steps, the aligned carbon nanotube film formed on the quartz or silicon substrate is transferred to the soft substrate, thereby producing a soft substrate aligned carbon nanotube film. By repeating the above-mentioned 3rd and 4th steps, the multilayer carbon nanotube film deposited on the quartz or silicon substrate can be transferred layer by layer to the soft substrate very conveniently, and a multi-piece soft substrate oriented carbon nanotube film can be produced.
本发明所述的利用现有的工艺生长多层定向碳纳米管，仅是为了能一次生成多层定向碳纳米管，然后通过本发明获得多片软基底定向碳纳米管膜，事实上利用现有的工艺生长单层定向碳纳米管，也同样适应于本发明。The present invention utilizes the existing process to grow multilayer aligned carbon nanotubes, only for the purpose of generating multilayer aligned carbon nanotubes at one time, and then obtains multi-sheet soft substrate aligned carbon nanotube films through the present invention. Some techniques for growing single-layer aligned carbon nanotubes are also applicable to the present invention.
本发明所述的胶粘剂，可以是不干胶或其它胶粘剂。The adhesive described in the present invention can be self-adhesive or other adhesives.
本发明所述的软基底，可以是金属膜、塑料、纸等柔软的材料，也可以就是直接用不干胶带，这样就不需要另外再涂覆胶粘剂。The soft substrate of the present invention can be soft materials such as metal film, plastics, paper, etc., or it can be directly used with self-adhesive tape, so that it does not need to be coated with adhesive in addition.
本发明所制作的软基底碳纳米管膜可以直接粘贴使用。例如可以粘贴在手机后盖上，起到吸波的作用；可以粘贴在电冰箱内，起到除臭作用等等。The soft base carbon nanotube film prepared by the invention can be pasted and used directly. For example, it can be pasted on the back cover of the mobile phone to absorb waves; it can be pasted in the refrigerator to deodorize and so on.
在本发明制作成的软基底碳纳米管膜基础上，还可以根据碳纳米管膜的不同用途，采用电镀、化学镀、等离子溅射等制膜工艺，在软基底的碳纳米管膜的表面制成一层金属膜，从而制造出具有定向排列的碳纳米管或金属的复合膜。在这种情况下，可用相应的溶剂将胶粘剂和软基底去除。On the basis of the soft substrate carbon nanotube film made in the present invention, it is also possible to use electroplating, electroless plating, plasma sputtering and other film-making processes according to the different purposes of the carbon nanotube film on the surface of the carbon nanotube film on the soft substrate A layer of metal film is made to produce a composite film with aligned carbon nanotubes or metal. In this case, the adhesive and the soft substrate can be removed with corresponding solvents.
本发明在制作单层碳纳米管膜方面，有其独特的优点，其工艺简单，制作成本低，生产效率高，可方便地用于各种不同的、复杂的场合，并可低成本地制作大面积的定向排列的碳纳米管膜。The present invention has its unique advantages in the production of single-layer carbon nanotube film, the process is simple, the production cost is low, the production efficiency is high, it can be conveniently used in various and complicated occasions, and can be produced at low cost Large-area aligned carbon nanotube films.

In this way, a single-layer carbon nanotube film has been prepared on the self-adhesive tape.
