NOVELTY - Polymer of graphene composite polyimide resin comprises 0.2-1.5 wt.% graphene, 1-5 wt.% titanium, 0.5-6 wt.% silicon sol, 2-10 wt.% fluorine-containing acrylate copolymer and polyimide resin allowance. USE - Polymer of graphene composite polyimide resin used for preparing polyimide film. ADVANTAGE - The resin has strong conductivity, stable microcosmic network structure, improved chemical modification, mechanical property and electrical property, smooth surface, strong conductivity effect, good antistatic property and high comprehensive mechanical strength, and can prepare polyimide film with 20-30 mu m thickness and 4.5x 101-3.7x 106 volume resistivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the polymer of graphene composite polyimide resin comprising slowly heating polyimide resin at 60-80 degrees C, adding fluorinated acrylate copolymer, rapidly stirring for 10-15 minutes, heating under low speed for 0.5-1 hours, re-cooling at 30 plus minus 5 degrees C, ultrasonically treating 10-12 minutes, and statically retaining for 2-4 hours to obtain first mixture; adding graphene into obtained first mixture at room temperature, and ultrasonically treating for 20-30 minutes each for every 15 minutes to obtain second mixture; grinding titanium dioxide into nano level, adding silica sol with composite filler at 45 degrees C for 0.5-1.5 hours to obtain third mixture; and slowly adding third mixture with second mixture under stirring conditions at 45-50 degrees C for 30 minutes, cooling at normal temperature and stirring.
