NOVELTY - Coating comprises 22-40 pts. wt. polyaniline, 15-21 pts. wt. polyvinyl alcohol, 0.6-2.5 pts. wt. graphene, 6-12 pts. wt. conductive filler, 7-15 pts. wt. modified attapulgite clay, 5-10 pts. wt. filler, 3-7 pts. wt. anti foaming agent and 35-52 pts. wt. solvent. USE - The coating is useful for capacitor (claimed). ADVANTAGE - The coating has good conductive effect, bonding firmness, thermal stability, corrosion resistance and extends shelf life of capacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing coating, comprising (i) taking polyaniline and polyvinylalcohol in ratio, adding into reaction kettle, heating to 60-80 degrees C, mixing, stirring for 0.5-1 hour, adding graphene and carrying out reaction by stirring for 1-2hours to obtain reaction product; (ii) mixing modified attapulgite clay with water, stirring well, placing under ultrasonic conditions, adding conductive filler by stirring slowly, after addition is complete, stirring continuously and dispersing for 20-30minutes to obtain mixture; and (iii) transferring reaction product into mixer, adding mixture, filler, defoaming agent and remaining solvent, stirring well, placing mixture, stirring at 1000-2000 revolutions/minute and dispersing for 30-40minutes.
