Bioinspired waterrepellent materials offer a wealth of opportunities to solve scientific and technological issues. Lotusleaf and pitcher plants represent two types of antiwetting surfaces, i.e., superhydrophobic and lubricantinfused
"slippery" surfaces. Here we investigate the functions and applications of those two types of interfacial materials. The superhydrophobic surface was fabricated
on the basis of a hydrophobic fumed silica nanoparticle/poly(dimethylsiloxane) composite layer, and the lubricantinfused "slippery" surface was prepared on the basis of silicone oil infusion. The fabrication, characteristics, and functions of both substrates were studied, including the wettability, transparency, adhesive force, dynamic droplet impact, antifogging, selfcleaning ability, etc. The
advantages and disadvantages of the surfaces were briefly discussed, indicating the most suitable applications of the antiwetting materials. This contribution is aimed at providing meaningful information on how to select waterrepellent
substrates to solve the scientific and practical issues, which can also
stimulate new thinking for the development of antiwetting interfacial materials.
