Abstract

In this work, poly (vinylidene fluoride)/protein composite films are prepared which is free standing and flexible. Nucleation of electroactive β-phase in poly (vinylidene fluoride) (PVDF) and consecutive surface morphological changes with different weight percentage of protein is systematically investigated. Finally, the PVDF/protein composite film is used to make a mechanical energy harvesting device. The flexible device produces 2.5 V open-circuit voltage under repeated hand punching. Thus, the device can be used for self-powered consumer electronics in near future.In this work, poly (vinylidene fluoride)/protein composite films are prepared which is free standing and flexible. Nucleation of electroactive β-phase in poly (vinylidene fluoride) (PVDF) and consecutive surface morphological changes with different weight percentage of protein is systematically investigated. Finally, the PVDF/protein composite film is used to make a mechanical energy harvesting device. The flexible device produces 2.5 V open-circuit voltage under repeated hand punching. Thus, the device can be used for self-powered consumer electronics in near future.

蛋白质促进聚偏氟乙烯中β相成核用于能量收集应用

本文制备了一种具有独立柔性的聚偏氟乙烯/蛋白质复合薄膜。系统地研究了聚偏氟乙烯(PVDF)中电活性β相的成核和不同重量百分比蛋白质的连续表面形态变化。最后，利用PVDF/蛋白质复合薄膜制作机械式能量收集装置。柔性装置在反复手冲下产生2.5 V开路电压。因此，该装置可以在不久的将来用于自供电的消费电子产品。本文制备了一种具有独立柔性的聚偏氟乙烯/蛋白质复合薄膜。系统地研究了聚偏氟乙烯(PVDF)中电活性β相的成核和不同重量百分比蛋白质的连续表面形态变化。最后，利用PVDF/蛋白质复合薄膜制作机械式能量收集装置。柔性装置在反复手冲下产生2.5 V开路电压。因此，该装置可以在不久的将来用于自供电的消费电子产品。
