Bioinspired Superhydrophobic Triboelectric Materials for Energy Harvesting

Abstract Drawing inspiration from nature has served as a crucial driving force behind human progress, enabling groundbreaking advancements and cross‐disciplinary integration through the emulation of biological superhydrophobic phenomena. Bioinspired superhydrophobic triboelectric materials stand out among advanced triboelectric materials due to their unique hydrophobic properties, exceptional moisture resistance, and remarkable electrical performance. However, the inherent complexity of natural phenomena and the need for refinement in bioinspired design pose significant challenges in the development of bioinspired superhydrophobic triboelectric materials. This comprehensive review delves into bioinspired superhydrophobic triboelectric materials from the perspectives of theoretical underpinnings, fabrication strategies, and cutting‐edge applications. Rooted in the interaction mechanisms between water molecules and triboelectric materials, the importance of enhanced hydrophobic properties is elucidated. A systematic overview of bioinspired superhydrophobic triboelectric materials’ construction strategies is presented, offering fresh perspectives and insights into the development and application of high‐performance triboelectric nanogenerators (TENGs). Finally, the current challenges and untapped opportunities in bioinspired superhydrophobic triboelectric materials are summarized to fully unlock their potential for applications in TENGs.
