AI Technical Summary
Existing carbon-based material preparation processes are complex, and commercial carbon materials have limitations in triboelectric nanogenerators, making it difficult to achieve efficient energy conversion and environmentally friendly energy solutions.
Using chrysalis-derived carbon composite material as the electrode layer, porous biochar material was prepared through pyrolysis and modification. Composite thin film electrodes were prepared by combining nanosolution and plasticizer, and then encapsulated in a triboelectric nanogenerator.
It significantly improves the energy conversion efficiency and charge storage capacity of triboelectric nanogenerators, realizes the recycling of agricultural waste resources, and provides low-cost, high-performance self-powered sensing applications.
