报告摘要：

Triboelectric materials are fundamental to the functioning of triboelectric nanogenerators (TENGs) and self-powered sensors. Engineering polymers like PTFE, PDMS, and polyamide are commonly used due to their significant triboelectric effects. However, the development of materials for TENGs faces two primary challenges: the need for innovative materials that exhibit high triboelectric effects, such as composites, and the limited application of traditional engineering polymers. For large-scale deployment, there is a requirement for substantial quantities of these polymers, which is problematic given the increasing restrictions on single-use plastics, particularly in Europe, where they will be limited starting from 2030. Cellulose-based materials have shown promise in addressing these challenges.
