报告内容简介

With the rapid development of electronics industry, the power consumption of portable devices decreases significantly, thus self-power devices become feasible. Moreover, in some special situations, replacement of batteries is not convenient or costly. As a result, the energy harvesting devices have attracted much attention in recent decades. In addition, in traditional precision device industry, high-performance strain sensors are a crucially important component. Therefore, materials with both sensing and energy harvesting functions are very attractive. Piezoelectric PVDF (Poly(vinylidene fluoride)) is a promising candidate due to its various merits, such as non-toxicity, high flexibility, recyclability, and high resistance ability to halogen, acid and fatigue, etc. In this study, we prepared PVDF nanocompositesusing three kindsofnanofillers by solution casting method, i.e., carbon nanotubes, graphene and carbon black. We obtainedtheimprovedpiezoelectricity of the PVDF nanocomposites which may have potential applications in the field of sensors and energy harvesting devices. The improvement mechanisms of piezoelectricity were explored in detail.
