报告摘要：Solid insulating materials are employed in various electrical and electronic applications, including electric power transmission/distribution system, electronic devices, electrical vehicles, etc. Recently, worldwide introduction of net-zero carbon policy requires the communities to provide solutions on eco-friendly, advanced and applicable dielectric materials. In this talk, firstly the current progress of environmentally friendly solid insulating materials will be briefly introduced. A full-life-cycle perspective (raw material, fabrication, utilization and retirement) will be used to facilitate the audience's understanding on this topic. Specifically, bio-based raw material, energy-saving ultraviolet light (UV) curing technique, long-lifetime insulating material and recyclable dielectrics will be discussed. Based on the above discussion, some future prospects is risen, including the suggestions on research topic, research methods and possible applications.

报告题目：High energy density nanocomposite materials based on ultrafine ferroelectric nanoparticles

报告摘要：Polymer-ceramic nanocomposite combines the high relative dielectric constant (εr) of the ceramic phase and the excellent breakdown strength and machinability of the polymer phase, which is considered as promising dielectric layer for high-performance energy-storage capacitors. One of the major problem for the promotion and application of nanocomposite is the low energy density, which is generally induced by the breakdown strength deterioration that caused by the aggregation or poor interface interaction of the filler phase. Ultrafine ferroelectric fillers provides high specific surface areas to improve the interface combination of the composite, therefore can effectively enhance both the polarization and dielectric strength of the matrix. Our work focus on the influence of the sub-10 nm ferroelectric fillers on the dielectric and energy storage performance of the composite. And we demonstrated that the ultimate sized nanocrystals can perform as superior high permittivity fillers in the nanocomposites for energy storage applications.

报告题目：High-Performance Triboelectric Nanogenerator and Tribophotonics

报告摘要：As the development of the Internet of Things (IoT), trillions of widely-distributed devices are integrated for health monitoring, biomedical sensing, environmental protection, infrastructure monitoring, and security, which require power supplies. To provide a sustainable power solution, triboelectric nanogenerator (TENG) has been developed since 2012 for high-efficiency mechanical energy harvesting from the ambient environment. The PI’s team has made significant contributions to fundamental studies about the triboelectric effect, discharge, and TENG output characteristics. and Multiple strategies to greatly enhance the output performance of TENG has been demonstrated, such as the high-pressure environment and the liquid-solid interface. On the other hand, the PI’s team also proposed and developed the concept of tribophotonics: tribo-charge induced tuning or generation of photons toward self-powered wireless sensing, which can be achieved through tunable liquid lens, liquid crystal, optical switch, tribo-induced electroluminescence (TIEL), and discharge. These studies will drive the further development of TENG technology for broad applications in blue energy harvesting, the IoT, human-machine interface, health & infrastructure monitoring, wearable & implantable electronics, towards high-efficiency self-powered systems.
