초록

Recent advancements in self-charging power devices highlight the potential of dielectric nanofillers in polymer matrixes to improve the performance of microsupercapacitor-triboelectric nanogenerator (TENG) integrated devices. However, achieving homogeneous dispersion of nanofillers into polymer matrixes remains a key bottleneck, often leading to inconsistent performance, reduced stability, and lower energy efficiency. This work presents an innovative chemical functionalization strategy covalently knitting MXene/graphene oxide (GO)/siloxene and MXene/reduced GO/siloxene networks into textile substrates, resulting in a consistent output performance and the development of a durable device. The single-electrode TENG delivered an output voltage of 380 V, a current density of 6.3 μA/cm2, a power density of 627 μW/cm2, and the transfer of 0.55 ± 0.03 μC of charge. The integrated device charged a voltage of 2.4 V after 110 s of continuous hand tapping, powering smart electronics. These results showcase the potential of chemically engineered heterostructures to address longstanding challenges in self-charging devices. © 2025 American Chemical Society.
