A preparing method of a polypyrrole magnetic conductive composite material

Abstract

A preparing method of a polypyrrole magnetic conductive composite material is disclosed. According to the composite material, carbon nanotubes participate polymerization of a pyrrole monomer, thus effectively improving dispersibility of the carbon nanotubes among polymers, effectively reducing agglomeration and increasing stability and strength of a finished-product material. Added hydroxylated iron adopting ferrocene as a raw material endows the finished-product material with good magnetic performance, thus expanding the using range of the finished-product material and enhancing functions of the finished-product material.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of a polypyrrole magnetoconductive composite 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...
