DETAILED DESCRIPTION - A high concentration graphene-polyaniline nano fiber compound dispersion preparing method involves adding oxidized graphite alkene for preparing polyaniline nano fiber dispersing graphite oxide and polyaniline nanometer fiber in distilled water and ultrasonically dispersing the obtained product to obtain graphene oxide dispersion liquid with concentration of 0.5 -2 milligram per milliliter and polyaniline nano fiber dispersion liquid with concentration of 0.1-0.3 milligram per milliliter, where a mass ratio of polyaniline nano fiber to the graphene oxide is 1-4:1. The graphene oxide dispersing liquid is dropped to the polyaniline nanometer fiber dispersion liquid and continuously and ultrasonically dispersed to the obtained product, where pH of the obtained product is regulated at 4 degrees C to obtain graphene-polyaniline nanometer fiber dispersion liquid with concentration of 0.5-1 milligram per milliliter. The high-concentration graphene-polyaniline nanometer fiber composite dispersion liquid is maintained at 50-80 degrees C under protection of nitrogen. A reducing agent is added to the composite dispersion liquid. The obtained product is reacted for 2-4 hours to obtain graphene under the ultrasonicpolyaniline nanometer fiber composite dispersion, where mass ratio of the graphene oxide and reducing agent is 10:5-9.
