Problems solved by technology

At present, in some scientific researches, polymer materials are usually processed by hot-melt method, but due to the mechanical stirring, the added carbon nanotubes are easily broken, especially when the hot-melt polymer material becomes When it is viscous, it is easier to break the carbon nanotubes when stirring, and the broken carbon nanotubes will lose their excellent electrical conductivity

Abstract

An electrical conducting polymer is prepared from carbon nanotubes and polymer in weight ratio of 1: (2-1000) through preparing carbon nanotube suspension, preparing polymer solution, mixing and moulding.

Description

technical field [0001] The invention relates to a conductive polymer and a preparation method thereof, in particular to a conductive polymer containing carbon nanotubes and a preparation method thereof. Background technique [0002] Carbon nanotubes are a new type of carbon structural material, specifically, a tubular structure with a diameter of several nanometers and a length of several microns. Due to its unique structure, it has many excellent properties unmatched by other substances, such as unique conductor or semiconductor conductivity, extremely high mechanical strength, hydrogen storage capacity and microwave absorption capacity, etc. [0003] With the rapid development of modern technology, the harm and potential harm caused by electromagnetic wave radiation to human beings is increasing day by day. High-performance conductive polymers can improve the resistance of electronic equipment to electromagnetic interference, suppress electromagnetic radiation, and realize...
