Abstract

The invention discloses a preparation method of a heat-proof phosphating polypyrrole doped conductive material. The preparation method comprises the following steps: 1) preparing an alkyl solution; 2)preparing an initiating agent solution; 3) preparing a phosphating monomer solution; 4) preparing a modified phosphating polypyrrole solution; 5) preparing the heat-proof phosphating polypyrrole doped conductive material. According to the preparation method of the heat-proof phosphating polypyrrole doped conductive material disclosed by the invention, aluminum nitride is treated by adopting trimethylolpropane, so that surface activation of aluminum nitride is improved, and then under a catalytic effect of p-methylbenzenesulfonic acid, high-temperature esterification on p-methylbenzenesulfonicacid and acid is realized, so that the bonding strength between aluminum nitride and polypyrrole is improved. According to the method, various heat-resistant stabilizing agents are added, so that theconductive material is high in temperature resistance and high in conductive stability.
