▎ 摘　　要

NOVELTY - Preparing PVDF/graphene flexible piezoelectric material comprises (i) dissolving a PVDF-based polymer in an organic solvent to obtain a PVDF-based polymer solution, adding a graphene dispersion and obtaining a uniform graphene/PVDF polymer dispersion and (ii) impregnating the PVDF/graphene dispersion with a fiber material, immersing the fiber material in the phase separation agent and drying. USE - The method is useful for preparing PVDF/graphene flexible piezoelectric material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing PVDF/graphene flexible piezoelectric generator, comprising (i) providing a PVDF/graphene piezoelectric material and (ii) providing a flexible conductive current collector on both sides of the PVDF/graphene piezoelectric material obtained in the step (i) and encapsulating.
