Self-disinfecting PDMS surfaces with high quaternary ammonium functionality by direct surface photoinitiated polymerization of vinylbenzyl dimethylbutylammonium chloride
Résumé
Vinylbenzyl dimethylbutylammonium chloride was successfully grafted and photopolymerized from a PDMS surface, in presence of benzophenone. The obtained surface exhibited quaternary ammonium density above 10 17 charge/cm 2 and very high hydrophilicity compared to ungrafted surfaces. Bacterial enumeration and fluorescence microscopy revealed an efficient contact killing of this surface against Escherichia coli, Staphylococcus aureus and Staphylococcus epidermidis.
