Self-Driven Gas Spreading on Mesh Surfaces for Regeneration of Underwater Superhydrophobicity

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(30), P. 40231 - 40242

Underwater superhydrophobic surfaces stand as a promising frontier in technological applications such drag reduction, antifouling, and anticorrosion. Unfortunately, the air film, known plastron, on these tends to be unstable. To address this problem, active approaches have been designed preserve or restore plastrons. In work, self-driven gas spreading mesh (SHM) surface is facilitate recovery of plastron. The immersed SHM can "wetted" by gas, even when plastron removed. We demonstrate that injected spread spontaneously along over large area, which greatly simplifies replenishment process. By incorporating locally coated gas-producing layer, we achieve rapid situ long-term immersion stability, extending lifespan at least 48 times. also provide framework for designing an with suitable structural dimensions spreading. Furthermore, asymmetric enables unidirectional transport capillary pressure difference. This shows excellent reduction properties (37.2%) has high slip coefficient (73.4%) after loss. facile scalable method expected broaden range potential involving nonwetting-related fields.
