Enhanced piezoelectric and electrodeformation properties of PVDF films fabricated by roll to roll process
Chao Zhang
Abstract:Abstractβ‐phase poly(vinylidene fluoride) (PVDF) film boasts excellent electrical properties and can be used in sensors, micro actuation, and energy harvesting. In this paper, high β‐phase PVDF films were stretched by stretch‐line equipment (roll to roll) and the β‐phase content can reach 60%, realizing the potential for large‐scale fabrication. Moreover, the electrical and electrostrictive properties of PVDF films before and after stretching are compared. The stretched film (PVDF‐R film) has better piezoelect… Show more
