NOVELTY - Preparation of polyionic liquid graphene hybrid material involves mixing N-vinyl heterocyclic compound with epichlorohydrin, heating, washing and drying to obtain single ionic liquid; dissolving single ionic liquid in methanol, adding sodium tetrafluoroborate crystals, and reacting; filtering, vacuum-evaporating and drying to obtain epoxy functional ionic liquid monomer; and adding epoxy functional ionic liquid monomer into deionized water graphene dispersion, mixing, adding azo graphene dispersion azobisisobutyronitrile in ethanol, heating, filtering, washing and drying. USE - Method for preparing polyionic liquid graphene hybrid material (claimed). ADVANTAGE - The material has excellent electrical property, simple and controllable reaction, and short processing time. DETAILED DESCRIPTION - Preparation of polyionic liquid graphene hybrid material comprises under nitrogen protection, mixing 1 pt. wt. N-vinyl heterocyclic compound with 0.88-1.18 pts. wt. epichlorohydrin, heating under reflux for 22-24 hours, washing and drying to obtain single ionic liquid; dissolving single ionic liquid in 10-20 pts. wt. methanol, slowly adding 0.48-0.71 pt. wt. sodium tetrafluoroborate crystals, and stir-reacting at 15-25 degrees C for 24-48 hours; filtering, vacuum-evaporating and drying to obtain epoxy functional ionic liquid monomer; and adding 0.05-1 pt. wt. epoxy functional ionic liquid monomer into deionized water graphene dispersion, mixing to get dispersed graphene, adding 0.001-0.1 pt. wt. azo graphene dispersion azobisisobutyronitrile in ethanol, heating under reflux for 22-24 hours, filtering, washing and drying.
