| description | The invention relates to the technical field of conductive materials, in particular to a polyvinylidene fluoride/graphene composite material, conductive slurry, a preparation method and application. The method comprises the following steps: preparing a graphene/vinylidene fluoride monomer mixed solution; uniformly mixing the obtained graphene/vinylidene fluoride monomer mixed solution, deionized water, an emulsifier and a pH regulator in a vacuum reaction chamber; introducing a vinylidene fluoride gas monomer into the vacuum reaction chamber at a preset temperature, adding an initiator into the mixed solution, and carrying out a polymerization reaction for a first preset time under a preset pressure; adding an initiator and a molecular regulator at a constant speed, and carrying out polymerization reaction for a second preset time; recovering the residual vinylidene fluoride gas monomer, and cooling to obtain a composite material emulsion; and adding a demulsifier into the composite material emulsion, filteri |
