Fe³⁺-Coordinated Chitosan-Hydrogel Networks for Highly Deformable and Enhanced Performance Triboelectric Nanogenerators.

ABSTRACT: Triboelectric nanogenerators (TENGs) have attracted a lot of attention recently because they can power wearable electronics and small energy-harvesting devices. However, the use of rigid materials has limited applicability in TENGs, particularly in flexible electronic devices. Hence, to address this challenge, flexible materials are gaining interest as an alternative to conventional rigid materials. This work introduces a hydrogel-based TENG that is easy to fabricate, offers high production efficiency, superior mechanical flexibility, and self-healing capabilities. The incorporation of Fe³⁺ ions into a crosslinked network of chitosan (CHI) and polyacrylic acid (PAA) macromolecular chains significantly enhances the hydrogel's conductivity and the TENG's output performance.
