A Succinct Review on Piezoelectric Characteristics of PVDF and its Copolymer PVDF-HFP

Abstract

Researchers are making attempts to develop a lightweight, shock resistance, portable, wireless sensors, and flexible wearable electronic devices. Piezoelectric nanogenerators are those which are used to convert mechanical into electrical energy and vice versa, which in turn meets the requirement of low-powered electronic gadgets. PVDF (Poly vinylidene difluoride) is found to be one of the versatile polymeric materials with intriguing characteristics and many technological applications. In recent days, Polyvinylidene difluoride and its copolymers like P(VDF-trifluoroethylene) and P(VDF-tetrafluoroethylene) are being explored extensively in order to produce energy harvesting devices. The present study deals with recent trends in the processing techniques of piezoelectric materials PVDF-HFP with different nano fillers in order to enhance its efficiency. This article may inspire several researchers to fabricate polymer composites of PVDF-HFP with different additives, which finds applications in several fields like shoe pad nanogenerator, biomedical, smart scaffolds, spin valve devices, and hybrid generators.

“…In contrast, synthetic piezoelectric polymer such as PVDF and its co-polymer (PVDF-TrFE) have been explored widely by researches to improve flexibility and piezoelectric property [24][25][26]. Extensive research is focused on the composite and hybrid structure of ZnO/PVDF to increase piezoelectric property.…”
