A novel strategy for preparing universal antifogging and antimicrobial coating is reported by the means of one-step coating and Ag nanoparticle (AgNP) formation in situ. A series of hydrophilic glycopolymers including poly(N-3,4-dihydroxybenzenethyl methacrylamide-co-2-deoxy-2(methacrylamido)glucopyranose) (P1s) and poly(N-3,4-dihydroxybenzenethyl methacrylamide-co-methacrylic acid-co-2-deoxy-2-(methacrylamido)glucopyranose) (P2s) were synthesized by sunlight-induced reverse addition-fragmentation chain transfer (RAFT) polymerization. With the ability to strongly 5 immobilize onto organic and inorganic surfaces (i.e., glass slide, silicon wafer, and polycarbonate) via catechol groups, P1s are very convenient to form superhydrophilic and transparent thin coatings, which result in a unique antifogging property. Additionally, the antimicrobial property is realized by in situ AgNPs forming P2 coatings, facilitated by the presence of carboxyl groups and catechol groups in the polymer chain, rendering it superior antimicrobial activity against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus microorganisms. This antifogging and antimicrobial thin coating shows strong prospects in medical and optical devices, with the extra benefits of avoiding potential pathogen infection in vitro or while in storage.
