Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>Water resistant polymer with adhesive behavior is reported to exhibit long‐term antimicrobial activities under diverse conditions. To obtain highly adhesive polymer with prolonged antimicrobial activities and catechol moiety, 2‐chloro‐3′, 4′‐dihydroxyacetophenone (CCDP) has been quaternized to poly(dimethylaminoethyl methacrylate) (PDMA). Later, for gaining the antimicrobial effects, the polymer (CCDP‐q‐PDMA) was quaternized with 1‐bromododecane (C12) [CCDP/C12‐q‐PDMA]. X‐ray photoelectron spectroscopy rectified the quaternization and adhesion of the polymer onto different substrates. The CCDP/C12‐q‐PDMA coated substrates exhibited remarkable bacterial killing efficiency against both Gram‐positive <italic>Staphylococcus aureus</italic> and Gram‐negative <italic>Escherichia coli, </italic> after incubation for 24 h. The remarkable antimicrobial activities exhibited in aqueous medium at 60°C for up to 60 days indicate the strong adhesiveness of CCDP/C12‐q‐PDMA on the substrate. Therefore, the synthesized polymer offers merit as a potential coating material, to protect a broad range of material from microbial contamination, for a prolonged period of time, under a highly stressed water environment. © 2014 Wiley Periodicals, Inc.
