Sustainable Materials for Liquid Repellent Coatings

A modern environmental safety approach requires the implementation of green or sustainable strategies, such as banning significantly lowering presence harmful substances on market in industrial environment. To date, majority highly performing solutions are still based fluorine chemistry, even with a growing effort to lower its impact. Economic costs, but also persistence, long-term degradation, and transformation environment can raise issues about medium- effects human health wildlife. Coatings high water oil repellence used worldwide daily life research fields, self-cleansing, anti-icing, anti-biofouling. The combination particular geometry surface structure low-energy materials results unique properties related range natural synthetic categories aiming build, when possible, fluorine-free world. This work revises recent key literature propose valid alternatives fluoro compounds terms repellence, well stability resistance physico-chemical agents. In this paper, like fatty acids waxes addressed together more systems silicon-based solutions, polymeric inorganic nanostructured coatings. Most revised papers deal topics fulfilling requirements mainly restricted repellent aqueous systems. Nevertheless, new strategies for providing suitable, oleophobic surfaces have been reported from small body literature.
