A carboxylated graphene oxide (GO-COOH) modified double-conductive polymer electrode material relates to a novel carboxylated graphene oxide modified polyaniline/polypyrrole (GO-COOPANI/PPY) as a super-capacitor electrode material. The carboxylated graphene oxide (GO-COOH) modified double-conductive polymer electrode material mainly settles technical problems of low compounding effect of a conductive high-polymer composite material, easy peroxidation and over-reduction reaction, low capacitance and short service life of a super-capacitor caused by factors of electrode degrading and reduction of oxidation/reduction potential along with time. A method according to the invention comprises the steps of preparing graphene oxide dispersion by means of an improved Hummers method and ultrasonic stripping, adding HBr, HOOC-COOH for preparing the carboxylated graphene oxide, preparing a GO-COOH-modified PANI/ATP, PPY/ATP composite material by means of a hard template method and an in-situ polymerization method, and performing template removing by means of HF acid. Through testing, the electrode material prepared according to the invention has advantages of higher capacitance, longer servicelife in cyclic use and remarkable electrochemical performance improvement. The carboxylated graphene oxide (GO-COOH) modified double-conductive polymer electrode material can be used as the super-capacitor electrode material with a potential application prospect.
