NOVELTY - A carbon oil comprises poly(3,4-ethylenedioxythiophene)-polystyrenesulfonic acid, acetylene black, graphene, hydroxypropyl cellulose, copper nanoparticles and solvent. USE - Carbon oil. ADVANTAGE - The carbon oil has low resistance, high temperature resistance and long service life, and good uniformity and adhesion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of the carbon oil comprising ultrasonically dispersing the graphene, acetylene and solvent to obtain dispersion liquid; and mixing the dispersion with the poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid, hydroxypropyl cellulose and copper nanoparticle and grinding to obtain the carbon oil.
