Understanding Dielectric Polymers based on Polyimide toward Improvement of Triboelectric Nanogenerator

Abstract

Triboelectric nanogenerator (TENGs), which can convert the mechanical energy into the electricity have been widely used as a representative means of energy harvesting. To access the key factors determining the triboelectric characteristics as a function of their work functions, polyimide-based materials with different functionalities were synthesized by using a sequence of chemical imidization for use in TENG applications.Moreover, we also synthesized the block copolymer based on polyimide to combine synergistic dual properties induced from each parent polymer. This study demonstrates the structure-property relationship in the TENGs.
