Preparation method of composite monomer modified conducting material

Abstract

The invention discloses a preparation method of a composite monomer modified conducting material. The preparation method comprises the following steps: treating pyrrole by virtue of paratoluenesulfonyl chloride to obtain sulfonyl pyrrole, enabling p-hydroxy benzaldehyde which is adopted as a raw material to have a bromination reaction, mixing the obtained modified monomer and the sulfonyl pyrrole, adding oleic acid modified carbon nanotubes in a polymerization process by adopting ferric trichloride as a catalyst and trichloromethane as a reaction solvent, so that inorganic filler such as carbon nanotubes can be effectively dispersed into the polymer, the compatibility between the inorganic filler and the polymer is improved, the agglomeration of the inorganic filler can be effectively improved, and the stability and strength of the finished product material can be improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of a composite monomer modified conductive material. Background technique [0002] Conductive polymer materials are polymer materials with conductive functions (including semiconductivity, metal conductivity and superconductivity) and conductivity above 10S / m. Polymer conductive materials have the characteristics of low density, easy processing, corrosion resistance, large-area film formation, and conductivity can be adjusted within a range of more than ten orders of magnitude. They can not only be used as substitutes for various metal materials and inorganic conductive materials , and has become an indispensable class of materials in many advanced industrial sectors and cutting-edge technology fields. After years of extensive research worldwide, the application of conductive polymers in new energy materials has achieved great development, but it is far f...

Problems solved by technology

This is mainly due to its poor processability and low stability, which seriously hinders the industrial application of conductive high-resolution materials.

Especially in the application of electrical components, conductive materials need to have good strength and stability, otherwise, no matter how good other properties are, they cannot be applied;
