Preparation method of transparent conductive film
The invention provides a preparation method of a transparent conductive film. The method comprises the following steps: laying an original carbon nanotube film with a set area on the surface of a substrate, and placing the original carbon nanotube film in a growth cavity; the substrate and the gas in the growth cavity are subjected to surface reconstruction, a facet is formed along with transportation of facet atoms forming the facet, and the facet is in a regular step shape on the surface of the substrate on the mesoscale; enabling the facets to interact with the original carbon nanotube film so as to remove impurities in the original carbon nanotube film, enabling at least part of the carbon nanotubes in the original carbon nanotube film to move under the driving of the facets, enabling the adjacent carbon nanotubes or tube bundles to be close to each other, and enabling the carbon nanotubes or tube bundles to be close to each other. And recombining the carbon nanotube network in the original carbon nanotube film to obtain the recombined carbon nanotube film. A more efficient conductive network is formed in the recombined carbon nanotube film obtained by the method, self-supporting can be realized, and large-area preparation of the transparent conductive film can be realized.
本发明提供了一种透明导电薄膜的制备方法。其中上述方法包括：将设定面积的原始碳纳米管薄膜铺设在衬底表面，并置于生长腔体中；衬底与生长腔体中的气体发生表面重构，伴随着构成刻面的刻面原子的输运，形成刻面，刻面在介观尺度上表现为衬底表面上的规律的台阶状；使刻面与原始碳纳米管薄膜发生相互作用，从而去除原始碳纳米管薄膜中的杂质，原始碳纳米管薄膜中至少部分碳纳米管在刻面的驱动下发生位置移动，相邻的碳纳米管或管束倾向于紧靠，使原始碳纳米管薄膜中的碳纳米管网络重组得到重组碳纳米管薄膜。通过此方法得到的重组碳纳米管薄膜，其内部形成了更加高效的导电网络，同时也能够实现自支撑，并且还可以实现透明导电薄膜的大面积制备。
