Water as an important renewable resource widely exists in human life in the form of raindrops, rivers, oceans, and so on. The efficient utilization of water energy has always been a hot spot in water-related researches. In recent years, triboelectric nanogenerators (TENG) show great potential in water energy harvesting due to its advantages of light weight, excellent flexibility, low cost, and high energy-collection efficiency. It is noteworthy that a hydrophobic interface can promote the complete separation of water and have the advantages of self-cleaning, anti-icing, anti-sticking, and anti-fogging, which is of great importance for the practical application of TENGs. This paper outlines the recent advances of water-driven TENGs based on hydrophobic interfaces, including the advantages of hydrophobic interfaces, materials used in hydrophobic interfaces, construction methods of effective hydrophobic interfaces, and explores the applications and future trends of water-driven TENGs based on hydrophobic interfaces.

水作为一种重要的可再生资源，以雨滴、河流、海洋等形式广泛存在于人类生活中。水能的高效利用一直是水相关研究的热点。近年来，摩擦纳米发电机（TENG）由于具有重量轻、柔韧性好、成本低和能量收集效率高等优点，在水能收集方面显示出巨大的潜力。值得注意的是，疏水界面可以促进水的完全分离，并具有自清洁、防结冰、防粘、防雾等优点，对TENGs的实际应用具有重要意义。本文概述了基于疏水界面的水驱动 TENGs 的最新进展，包括疏水界面的优点，
