▎ 摘　　要

NOVELTY - Flexible piezoelectric material comprises 60-80 pts. wt. polyvinylidene fluoride, 30-50 pts. wt. nylon 1111, 1-5 pts. wt. rare earth modified graphene oxide, 10-2 pts. wt. polyamideimide grafted bismuth-sodium-titanium(III) oxide- barium titanate (Bi0.5Na0.5TiO3-BaTiO3) and 2-4 pts. wt. polybutylene succinate. The rare earth modified graphene oxide is treated with a silane coupling agent. USE - Used as fFlexible piezoelectric material. ADVANTAGE - The material has good piezoelectric performance and good flexibility; maintains the flexibility of the polymer; and improves the piezoelectric performance of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for flexible piezoelectric material based on polyvinylidene fluoride.
