Green hydrophobic and superhydrophobic coatings and surfaces for water related applications: A review

Water-resistant coatings and surfaces are ubiquitous in modern life. They are used in consumer goods, food packaging, medical devices and other technical, as well as scientific applications. The introduction of per- and polyfluoroalkyl substances (PFAS) several decades ago was the key technology making this innovation possible. PFAS coatings are low surface energy, hydrophobic coatings, which exhibit low friction and antiwetting properties. PFAS materials and coatings have been extensively used to realize extreme anti-wetting surfaces, i.e. surfaces which can repel water (superhydrophobic), as well as other low surface tension liquids and oils (superoleophobic). Such materials and surfaces are ideal for…
