Antimicrobial properties of novel n-halamine siloxane coatings

摘要: Antimicrobial coatings on a wide variety of hard and soft substrates were prepared by exposing surfaces treated with novel N-halamine siloxane precursor monomers macro-monomers to oxidative halogen solutions. Suspensions range bacterial, viral, fungal yeast micro-organisms applied the halogen-charged for defined intervals, before recovery quantification surviving microbes using appropriate neutralisation culture techniques. The biocidal exhibited powerful, broad-spectrum antimicrobial properties, inactivating most challenge in contact times measured minutes hours, rather than extended incubation periods usually associated substrate-bound agents. effects also demonstrated prevent odour caused bacterial generation ammonia an experimental simulation urine-soaked nappy pad. Contact efficacy related bound concentrations per unit surface area. Potential benefits these rechargeable cover range, from limiting contamination environmental disease agents healthcare or food service facilities, controlling mildew bathrooms, preventing formation incontinence pads.
