Nanofibers with good softness and high surface specific area are excellent choices for wearable triboelectric nanogenerator (TENG), despite that the deformability and durability remain challenging in seamless integration with daily textiles/clothes. Herein, we propose a physical interlocking strategy to realize a self-interlocked stretchable, breathable and waterproof nanofibers-membrane by simultaneous electrospinning of poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and electrospraying of styrene-ethylene-butylene-styrene (SEBS). The electrosprayed SEBS microspheres serve as the elastic binders and hydrophobic modifiers for enhancing stretchability and waterproofness of the electrospun PVDF-HFP fibers network. By means of a printable electrode consisted of liquid metal (gallium indium tin particles) and silver flakes, a stretchable nanofibers-based TENG (SNF-TENG) with high triboelectric output (85 V, 219.66 mW m⁻²) and electrical durability was demonstrated, capable of harvesting energy from human motions and flowing water, powering 200 commercial LEDs and an electronic watch. The stretchable nanofibers membrane shows favorable mechanical compliance, which can be facilely integrated onto a stretchable textile to fabricate textile-TENG, promising for comfortable wearable applications for power sources, smart raincoat, self-powered e-skin and tactile interactive interfaces.

具有良好柔软性和高比表面积的纳米纤维是可穿戴式摩擦电纳米发生器（TENG）的绝佳选择，尽管其变形性和耐用性在与日常纺织品/衣服无缝结合方面仍然具有挑战性。在这里，我们提出一种物理联锁策略，以通过同时电纺聚偏二氟乙烯-共-六氟丙烯（PVDF-HFP）和电喷涂苯乙烯-乙烯-丁烯-苯乙烯来实现可自锁的可拉伸，透气和防水的纳米纤维膜（SEBS）。电喷涂SEBS微球用作弹性粘合剂和疏水改性剂，可增强电纺PVDF-HFP纤维网络的拉伸性和防水性。通过由液态金属（镓铟锡颗粒）和银薄片组成的可印刷电极，^{展示了（-2}）和电气耐久性，能够从人体运动和流动的水中收集能量，为200个商用LED和电子表供电。可拉伸的纳米纤维膜表现出良好的机械柔韧性，可以轻松地集成到可拉伸的纺织品上以制造TENG纺织品，有望在电源，智能雨衣，自供电电子皮肤和触觉交互界面的舒适可穿戴应用中实现。
