Nanotechnologies for Synthetic Super Non‐Wetting Surfaces

Wettability is modulated by the relief of the surface that can intensify the wetting or non-wetting behavior. Creating a synthetic super non-wetting surface has been proved to be extremely challenging. Nanotechnologies are playing an increasingly prominent role in introducing new coatings with specialized properties and enhanced performances. According to a recent market research report from Future Markets Research Inc. these advanced coatings are likely to replace traditional coatings “in the medium to long-term in end-use segments such as packaging, anti-microbial coatings, architectural coatings, industrial manufacturing, marine, wood, auto-refinish, transportation and protective coatings”. At thermodynamic equilibrium, the wettability of a smooth solid surface is typically quantified by the measurement of the so-called “Young contact angle” of a sessile liquid droplet.
