超疏水设计可使铝金属管“永不沉没”

Core Viewpoint - The article discusses the development of superhydrophobic aluminum tubes that can "never sink," allowing them to float on water even in harsh environments or when structurally damaged [1]. Group 1: Technology Development - Researchers at the University of Rochester have utilized laser treatment to create a superhydrophobic surface on aluminum tubes, enabling them to float on water [1]. - The surface structure mimics natural superhydrophobic organisms, such as lotus leaves, which can repel water [1]. - The newly developed tubular structure can "store" more air compared to previously developed disc-shaped floating aluminum components, enhancing its buoyancy [1]. Group 2: Performance and Applications - The aluminum tubes maintain their floating ability even when subjected to extreme angles or when submerged for extended periods, demonstrating resilience against turbulent sea conditions [1]. - Various lengths of aluminum tubes were tested, with the longest reaching half a meter, indicating versatility in application [1]. - The tubular components can be easily connected, making them suitable for manufacturing buoys, vessels, and floating platforms [1].
