手机又不小心掉水里了,心疼吧?不过以后就不用担心这个问题了。美国罗彻斯特大学的两名科学家发明了一项新技术,可以让金属不再粘水。他们用激光束照射金属,在其表面“雕刻”出平行排列的微型沟槽,这些沟槽深75微米,间距100微米。这样的微观结构赋予了金属不沾水的特性。而且,与普通疏水材料不同,它无需任何化学涂层,可永久性地保持疏水特性,非常适合那些不易维护又需要长时间保持功能特性的金属
Phone accidentally out of water, distressed, but do not have to worry about this issue later. Two scientists at the University of Rochester invented a new technology that will keep the metal from sticking. They irradiated the metal with a laser beam and “engraved” on its surface microtrenchs arranged in parallel with 75 micrometers deep and 100 micrometers apart. This microstructure gives the metal a water-free character. Moreover, unlike conventional hydrophobic materials, it does not require any chemical coating and permanently retains hydrophobic properties, making it ideal for metals that are less maintainable and retain their functional properties over time
