摘要
Polymers are chain-like molecules comprised of repeating monomer units connected to each other. The surfaces of polymer materials reflect their intrinsic physical and chemical properties, which are close to the properties of biological surfaces and interfaces. Consequently, polymers are considered ideal organic materials to obtain bio-mimetic superwetting properties (i.e. superhydrophobicity, superoleophobicity, superhydrophobicity, or superoleophobicity). In this chapter, we introduce the recent developments on superwetting polymer surfaces according to various applications across fields from scientific research to industry (self-cleaning surfaces, capture of circulating tumor cells, underwater capture of air and methane, oil/water separation, fog-collecting systems, insect robots with the ability to walk on water, switchable water droplet transport systems, artificial ion channels to control ion transport and for energy conversion, etc.). Some superwetting phenomena on bio-surfaces and interfaces will be briefly discussed as the source of inspiration for their artificial counterparts (e.g. lotus leaves, rose petals, spider-silk, fog collection by cactus, water-strider legs, ion channel proteins). Finally, a summary on superwetting polymer surfaces together with the prospect of their future will be given.
