▎ 摘  要

NOVELTY - An antistatic crosslinked graphene film comprises 14-20 pts. wt. antistatic emulsion, 10-13 pts. wt. graphene oxide, 65-70 pts. wt. PTFE, 2-3 pts. wt. trifluoroethyl methacrylate, 0.7-1 pt. wt. azobisisobutyronitrile, 1-2 pts. wt. 4,4'-diphenylmethane diisocyanate, 0.8-1 pt. wt. trichlorodiphenylurea, 0.1-0.2 pt. wt. zinc acetylacetonate, and 3-5 pts. wt. allyl polyethylene glycol. USE - Antistatic crosslinked graphene film. ADVANTAGE - The antistatic crosslinked graphene film improves the dispersion compatibility between graphene and PTFE, and has improved mechanical stability, high safety and excellent comprehensive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of antistatic crosslinked graphene film, which involves (1) taking azobisisobutyronitrile, adding to 6-9 times the weight of isopropanol, and uniformly stirring, (2) mixing graphene oxide and allyl polyethylene glycol, adding deionized water of 14-20 times the weight of the mixed material, and ultrasonically treating for 3-5 minutes to obtain graphene dispersion liquid, (3) taking trichlorodiphenylurea, adding to 5-7 times the weight of dimethylformamide, and uniformly stirring to obtain amide solution, (4) mixing amide solution and azobisisobutyronitrile-isopropanol solution, uniformly stirring, adding 4,4'-diphenylmethane diisocyanate to a reactor, adding PTFE and antistatic emulsion, adjusting the temperature of the reactor to 90-95 degrees C, maintaining the temperature for 1-2 hours, discharging and cooling to obtain graphene-modified PTFE, and (5) mixing the graphene-modified PTFE and the remaining raw materials, uniformly stirring, feeding to a extruder, and casting to form film.
