Realizing energy harvesting from water flow using triboelectric generators (TEGs) based on our daily wearable fabric or textile has practical significance. Challenges remain on methods to fabricate conformable TEGs that can be easily incorporated into waterproof textile, or directly harvest energy from water using hydrophobic textile. Herein, a wearable all‐fabric‐based TEG for water energy harvesting, with additional self‐cleaning and antifouling properties is reported for the first time. Hydrophobic cellulose oleoyl ester nanoparticles (HCOENPs) are prepared from microcrystalline cellulose, as a low‐cost and nontoxic coating material to achieve superhydrophobic coating on fabrics, including cotton, silk, flax, polyethylene terephthalate (PET), polyamide (nylon), and polyurethane. The resultant PET fabric‐based water‐TEG can generate an instantaneous output power density of 0.14 W m−2 at a load resistance of 100 MΩ. An all‐fabric‐based dual‐mode TEG is further realized to harvest both the electrostatic energy and mechanical energy of water, achieving the maximum instantaneous output power density of 0.30 W m−2. The HCOENPs‐coated fabric provides excellent breathability, washability, and environmentally friendly fabric‐based TEGs, making it a promising wearable self‐powered system.

可穿戴式全织物摩擦发电机，用于水能收集
基于我们的日常可穿戴织物或纺织品，使用摩擦发电机（TEG）实现从水流中收集能量具有现实意义。制备顺应性TEG的方法仍然存在挑战，该方法可以轻松地掺入防水纺织品中，或者使用疏水性纺织品直接从水中收集能量。本文首次报道了一种可穿戴式全织物TEG，用于水能收集，具有附加的自洁和防污性能。疏水性纤维素油酸酯酯纳米颗粒（HCOENPs）由微晶纤维素制成，是一种低成本且无毒的涂料，可在包括棉，丝绸，亚麻，聚对苯二甲酸乙二酯（PET），聚酰胺（尼龙）和聚氨酯的织物上实现超疏水性涂层。负载电阻为100MΩ时为−2。进一步实现了基于全织物的双模TEG，以收集水的静电能和机械能，从而实现了0.30 W m -2的最大瞬时输出功率密度。HCOENPs涂层的织物可提供出色的透气性，可洗性和环保的基于织物的TEG，使其成为一种有前途的可穿戴自供电系统。
