Abstract

With the growing exploitation of marine resources, the deployment of underwater equipment is increasing substantially. As a result, reducing underwater friction and enhancing vehicle speed and operational efficiency have become crucial research areas. This study introduced a deformable superhydrophobic composite surface material consisting of modified nanoscale titanium dioxide (TiO₂) particles and polydimethylsiloxane (PDMS) by spraying to form a rough surface, which supported the formation of a stable superhydrophobic air film and exhibited excellent drag reduction properties. This surface attained a maximum drag reduction rate of 47.33%. Additionally, Moreover, the superhydrophobic surface (SHS) demonstrated exceptional stability in underwater environments, along with remarkable anti-icing and anti-fouling properties. These results highlight the significant potential of this technology for underwater drag reduction applications.

一种具有防污防冰性能的可控变形PDMS/TiO2超疏水减阻涂料

随着海洋资源的不断开发，水下设备的部署也在大幅增加。因此，减少水下摩擦，提高航行器的速度和作业效率已成为重要的研究方向。本研究引入了一种由改性纳米级二氧化钛（TiO2）颗粒和聚二甲基硅氧烷（PDMS）通过喷涂形成粗糙表面的可变形超疏水复合表面材料，该材料支持形成稳定的超疏水空气膜，并具有优异的减阻性能。该表面的最大减阻率为47.33%。此外，超疏水表面（SHS）在水下环境中表现出卓越的稳定性，以及卓越的防冰和防污性能。这些结果突出了该技术在水下减阻应用中的巨大潜力。
