压电聚合物聚偏氟乙烯-三氟乙烯(P(VDF-TrFE))作为聚偏氟乙烯(PVDF)典型的共聚物,具有优异的压电性能、机械性能及生物相容性.因此基于P(VDF-TrFE)静电纺压电网膜的柔性压电传感器与能量收集器在可穿戴电子设备、智能纺织品及医疗健康系统等领域有着广阔的前景,能够将触觉/压力、应变、声波甚至生理微振动等信号转换为电学信号或低功率的电能.本文旨在深入分析P(VDF-TrFE)压电性能的机制,总结各种提升静电纺P(VDF-TrFE)纳米纤维压电性的策略,全面概述P(VDF-TrFE)基柔性压电传感与能量收集方面的应用,特别是在压力与触觉传感、声传感、生物组织传感、生理微振动传感及能量收集等领域的研究进展.阐述了静电纺压电聚合物纳米纤维的新兴应用场景,并讨论了该领域目前的挑战和未来前景.
Abstract
Poly(vinylidenefluoride-co-trifluoroethylene)(P(VDF-TrFE))is a copolymer of polyvinylidene fluoride(PVDF)that exhibits outstanding piezoelectric properties,mechanical properties,and biocompatibility.Therefore,the flexible piezoelectric sensors and energy harvesters based on P(VDF-TrFE)have a promising future in the fields of intelligent textiles,wearable electronic devices and medical and health systems.These devices can convert signals such as tactile,pressure,strain,acoustic waves or even physiological micro-vibrations into electrical signals or low-power electrical energy.This paper aims to provide an in-depth analysis of the mechanism of P(VDF-TrFE)piezoelectric properties,summarize various strategies to enhance the piezoelectricity of electrostatically spun P(VDF-TrFE)nanofibers,and provide a comprehensive overview of the applications of P(VDF-TrFE)-based flexible piezoelectric sensing and energy harvesting.Specifically,research advances in the areas of pressure and tactile sensing,acoustic sensing,biological tissue sensing,physiological micro-vibration sensing,and energy harvesting are summarized.Finally,the emerging application scenarios of electrospun piezoelectric polymer nanofibers are illustrated,the current challenges and future prospects in this field are discussed.
