Superhydrophobic coatings A new siloxane/polyurea coating design leverages microphase separation and an epoxy armour layer to achieve long-term su-perhydrophobicity, even under me-chanical abrasion and chemical ex-posure. The best-performing system achieved a contact angle of 154º, maintaining water repellency after stress tests and immersion in acidic/alkaline solutions. Guo, Q. et al., Progress in Organic Coat-ings, Volume 200, March 2025. Anti-fouling Chinese researchers developed zwitterion-containing amphiphilic copolymers that inhibit microbial growth without biocides. The optimised formula achieved over 95% antibacterial efficiency and remained effective after 147 days in ...
