Reconfiguring Hierarchical Porous Architecture of 2D Metal Nanosheets for Multifunctional Triboelectric Nanogenerators.

ABSTRACT: 2D single-crystalline metal nanosheets are a promising platform for self-powered electronics, yet their potential for triboelectric nanogenerators (TENGs) remains unexplored. A key challenge in TENGs is overcoming low current output and limited durability. A hierarchical porous copper nanosheet-based TENG (HPC-TENG) is reported to substantially enhance triboelectric performance through a unique structural design. The method uses a simple spray-coating process to create a hierarchical porous conductive film from 2D copper nanosheets (Cu NSs). By infiltrating this film with polydimethylsiloxane (PDMS), interfacial contact is maximized, significantly boosting charge generation during mechanical cycling. The HPC-TENG achieves a remarkable 590% enhancement in electrical output compared to conve
