Problems solved by technology

Through strong acid treatment, the carbon nanotubes will be damaged to a certain extent, and the use of surfactant treatment will make the surfactant difficult to remove in the final carbon nanotube / conductive polymer composite
Therefore, the performance of carbon nanotube / conducting polymer composites obtained after treatment with strong oxidizing acids or surfactants will be affected
In addition, because carbon nanotubes are easy to agglomerate, they have not been well dispersed at present. Therefore, the carbon nanotubes in the carbon nanotube / conductive polymer composite material prepared by the prior art usually do not form a good conductive network, and The spacing between some adjacent carbon nanotubes is relatively large, and the contact between them is poor, so the excellent electrical conductivity and thermal conductivity of carbon nanotubes cannot be fully utilized, resulting in relatively low internal resistance of the carbon nanotube / conductive polymer composite. Large, low specific capacity

Abstract

The invention discloses a preparation method for a carbon nano tube / conducting polymer composite material, which comprises the following steps: providing a carbon nano tube film; and adopting electrochemistry in-situ polymerization to composite conducting polymer on the carbon nano tube film to prepare the carbon nano tube / conducting polymer composite material.

Description

technical field [0001] The technical solution relates to a preparation method of a carbon nanotube / polymer composite material, in particular to a preparation method of a carbon nanotube / conductive polymer composite material. Background technique [0002] Since the discovery of carbon nanotubes (Carbon Nanotubes, CNTs) by Iijima of Japan's NEC Corporation in 1991 (Iilima S., Nature, 1991, 354, 56-58), it has immediately attracted great attention from the scientific and industrial circles. Carbon nanotubes have excellent mechanical and optoelectronic properties and are considered ideal additives for composite materials. Carbon nanotube / polymer composite material has become the focus of scientific research in the world (Ajjayan P.M., StephanO., Colliex C., Tranth D.Science.1994,265,1212-1215: Calvert P., Nature, 1999,399,210 -211). Carbon nanotubes are used as reinforcements and conductors, and the composite materials formed have antistatic, microwave absorption and electroma...
