Abstract

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.

用新型MXene/氧化石墨烯/硅氧烷框架在纺织品上推进自供电装置：桥接化学和可持续性

自充电电源器件的最新进展突出了聚合物基体中介电纳米填料在提高微超级电容器-摩擦电纳米发电机（TENG）集成器件性能方面的潜力。然而，实现纳米填料在聚合物基体中的均匀分散仍然是一个关键的瓶颈，通常会导致性能不一致、稳定性降低和能效降低。这项工作提出了一种创新的化学功能化策略，将MXene/氧化石墨烯(GO)/硅氧烷和MXene/还原氧化石墨烯/硅氧烷网络共价编织到纺织基材中，从而实现一致的输出性能和耐用设备的开发。单电极TENG输出电压为380 V，电流密度为6.3 μA/cm2，功率密度为627 μW/cm2，电荷转移量为0.55±0.03 μC。该集成设备在持续用手轻敲110秒后充电2.4 V电压，为智能电子设备供电。这些结果显示了化学工程异质结构在解决自充电设备中长期存在的挑战方面的潜力。
