A method of preparing a nitrogen-containing polymers for electrode materials for supercapacitors

The present invention relates to a method for preparing a nitrogen-containing polymers for electrode materials for supercapacitors, the following steps:.. A under stirring, bromine was added to absolute ethanol, cooled to obtain a solution A; b in under inert gas protection, pyrrole was added dropwise to the solution a, stirring was continued for a reaction to prepare an ethanol solution of pyrrole much bromo B; C ethanol solution B polybrominated pyrrole all ethanol was distilled off, to obtain black. C powdery solids;. D powdery solid black C under inert gas protection, temperature rise, heat treatment, to obtain a nitrogen-containing polymer. In the present invention as a raw material pyrrole, pyrrole by bromination, debromination cyclization synthesized polypyrrole traditional novel nitrogen-containing polymer which is different from the polymerization of the pyrrole ring of the one-dimensional direction. The nitrogen-containing working electrode body nitrogen polymer distribution, high tap density, the nitrogen-containing polymer prepared by using a high specific capacity and good cycle stability, suitable for use in assembling a supercapacitor.
