 Slips, slippery liquid-infused porous surfaces have been developed with the aim of reducing friction and drag, which can be applied in many areas such as nautical, industrial, medical, and more. The technology works by coating a surface with a lubricant that allows it to slide easily over other surfaces. This lubricant is then infused into the surface, creating a porous structure that increases its ability to repel water and reduce drag. Additionally, the lubricant can be tailored to suit specific needs, such as anti-corrosion or anti-icing. Recent developments include using slips to create coatings that can be used in medical treatments, such as for treating burns. This article was authored by Li Xia, Xiuzhuang, and Zhiguanguo.
