This project focuses on improving the electric output of the solid/liquid interface triboelectric nanogenerator for wave energy harvesting and solving the problem of reduction in conversion efficiency due to surface matter adsorption. It is proposed to carry out theoretical and practical research on the core scientific issue of how to improve and long-term resident triboelectric charge at the solid/liquid interface by introducing the preparation of bio-inspired self-cleaning modification on solid/liquid interface triboelectric nanogenerator surface. From increasing the solid/liquid interface triboelectric charge density by microstructure preparation, to reduce the surface adsorption of substances, and then to the antifouling bionic self-cleaning surface with micro-nano hierarchical structures, from outward appearance to inner essence, layer upon layer optimization, until the final bio-inspired super effective self-cleaning surface enhanced high output solid/liquid interface triboelectric nanogenerator. This project combines basic scientific issues with actual preparation technology, opening up a new way of thinking for surface adsorption, expecting to obtain a variety of high power generation performance and antifouling for triboelectrification surface, and promote the practical process of water wave energy harvesting.
