Depleting fossil energy sources and conventional polluting power generation pose a threat to sustainable development. Hydroelectricity generation from ubiquitous and spontaneous phase transitions between liquid and gaseous water has been considered a promising strategy for mitigating the energy crisis. Fibrous materials with unique flexibility, processability, multifunctionality, and practicability have been widely applied for fibrous materials-based hydroelectricity generation (FHG). In this review, the power generation mechanisms, design principles, and electricity enhancement factors of FHG are first introduced. Then, the fabrication strategies and characteristics of varied constructions including 1D fiber, 1D yarn, 2D fabric, 2D membrane, 3D fibrous framework, and 3D fibrous gel are demonstrated. Afterward, the advanced functions of FHG during water harvesting, proton dissociation, ion separation, and charge accumulation processes are analyzed in detail. Moreover, the potential applications including power supply, energy storage, electrical sensor, and information expression are also discussed. Finally, some existing challenges are considered and prospects for future development are sincerely proposed.
化石能源的枯竭和传统污染发电对可持续发展构成威胁。利用液态水和气态水之间普遍存在的自发相变进行水力发电，被认为是缓解能源危机的一种有前景的策略。具有独特柔韧性、可加工性、多功能性和实用性的纤维材料已被广泛应用于基于纤维材料的水力发电（FHG）。在这篇综述中，首先介绍了FHG的发电机制、设计原理和电增强因素。然后，展示了包括一维纤维、一维纱线、二维织物、二维膜、三维纤维框架和三维纤维凝胶在内的各种结构的制备策略和特性。之后，详细分析了FHG在集水、质子解离、离子分离和电荷积累过程中的先进功能。此外，还讨论了其潜在应用，包括电源、储能、电传感器和信息表达。最后，考虑了一些现有挑战，并真诚地提出了未来发展的前景。
