제목 High-Performance Stretchable Piezoelectric Nanogenerators Based on Polymer-Ceramic Composites
초록  Recently, piezoelectric materials have attracted great attention as an active material in piezoelectric devices such as wearable electronics. As the power consumption of electronics is lower to mW and even μW in future, implementing a piezoelectric power system and convert the body’s mechanical energy into electrical energy is a promising strategy to extend the life of the battery. Recently, flexible or stretchable piezoelectric nanogenerators (PNGs) have emerged as next-generation energy harvester, essentially requiring the PNGs themselves to be deformable and stretchable in order to adapt to common human motions. In this work, we report high-performance stretchable PNGs based on a composite thin film, comprising of amine-functionalized PZT nanoparticles (NPs) and a thermoplastic triblock copolymer grafted with maleic anhydride. The chemically reinforced composites achieves the formation of a highly well-dispersed PZT NPs within polymer matrix as well as the enhancement of the stress applied to PZT NPs. Our proposed approach is an unprecedented improvement in the composite-based PNG research for self-powered flexible energy source to realize the wearable electronics and sensors in ubiquitous wireless communication.
