Polymer microspheres having bio-based cardanol moiety were prepared via suspension polymerization of 2-hydroxy-3-cardanylpropyl methacrylate (CM). The incorporation of the cardanol moiety into polymer microspheres could impart the bactericidal properties and the microspheres were found to have a cross-linked structure formed during the suspension polymerization by the reactions between the double bonds in the cardanol moieties. The polymer microsphere itself prepared by CM and the polymer film prepared by casting the polymer microsphere suspension were found to have very high antibacterial activity against E.coli. The bactericidal properties of the polymer films were found to be caused by the disruption of cell wall by contactkilling without any leaching of antibacterial moieties. Furthermore, all the polymeric films from microsphere of the polymer and copolymers showed sufficient biocompatibility, regardless of their monomer compositions.
