超疏水设计可使铝金属管“永不沉没”

Core Viewpoint - Researchers in the United States have developed a laser-treated aluminum tube that exhibits superhydrophobic properties, allowing it to "never sink" and float on water even in harsh environments or when structurally damaged [1] Group 1: Technology Development - The research team from the University of Rochester has published findings in the journal Advanced Functional Materials, detailing how they etched micro and nano-scale pits on the surface of aluminum tubes using lasers [1] - This surface structure creates a stable air layer in water, enabling the aluminum tube to float [1] Group 2: Performance Comparison - Compared to previously developed disc-shaped floating aluminum components, the new tubular design can "store" more air, enhancing its buoyancy [1] - The tubular structure maintains its floating capability even when subjected to extreme angles or vertical immersion in water, demonstrating resilience against turbulent sea waves [1] Group 3: Testing and Applications - Various lengths of aluminum tubes were tested, with the longest measuring half a meter [1] - The tubular components are easy to assemble and can be utilized in the manufacturing of buoys, vessels, and floating platforms [1]
