Properties and Applications of Flexible Poly(Vinylidene Fluoride)-Based Piezoelectric Materials

Poly (vinylidene fluoride) (PVDF) is a kind of semicrystalline organic polymer piezoelectric material. Adopting processes such as melting crystallization and solution casting, undergoing post-treatment annealing, stretching, polarization, PVDF films with high crystallinity response level can be realized. As material, shows excellent mechanical properties, chemical stability biocompatibility, light in weight, easily prepared, which designed into miniaturized, chip-shaped integrated devices. It has wide range applications self-powered equipment sensors, nanogenerators currently research hotspot for use flexible wearable or implantable materials. This article mainly introduces the crystal structures, properties their devices
