Towards PFAS-free Water Repellent Coatings

The replacement perfluorinated substances (PFAS) as chemical applied in anti-adhesive and hydrophobic applications has become an urgent need, due to raising concerns due to their potential hazard for human health and environment. In this framework, chitosan-based coatings represent a promising alternative because of their properties of non-toxicity, biodegradability, and sustainability as raw materials. During the talk, we will present our strategies to prepare modified chitosan-based coatings. The application of an innovative and sustainable deposition method demonstrates to be effective in tuning the coating properties of transparency and superhydrophobicity, combining durability under physical abrasion.
