In this work,the one-step stereochemical antimicrobial finishing of cotton textiles (CT) was achieved by the oxidative copolymerization of a dopamine-menthol derivative (DAM) and dopamine (DA).The obtained DAM-modified CT (P(DAM-co-DA)-CT) exhibited broad-spectrum microbial anti-adhesion properties against bacteria (E.coli and P.aeruginosa),including superbugs (MRSA and VREF),and fungi (A.niger,A.flavus,M.racemosus and P.chrysogenum).Because of its unique stereochemical antimicrobial mechanism,the obtained P(DAM-co-DA)-CT is a non-releasing antimicrobial material that causes no skin sensitization and exhibits good biocompatibility.The coating was also found to enhance the UV-resistant and mechanical properties of the CT.Furthermore,it displayed durable washing fastness and antimicrobial properties after the endurance of 30 laundering cycles.The observed achievements provide a broader understanding of stereochemical antimicrobial surfaces and endow this method with widerapplications.
