摘　　要：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 UVresistant 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 wider applications.
