摘要:A method for forming a polymeric coating on a substrate surface, which methodcomprises the steps of activating at least one polymerisable organic acid or acidanhydride monomer comprising one or more acid and/or acid anhydride groups and atleast one polymerisable group and/or at least one polymerisable organic base monomercomprising one or more basic groups and at least one polymerisable group by subjectingsaid monomers to a soft ionisation plasma process such as by low pressure pulsedplasma or atmospheric pressure glow discharge treatments; and depositing the activatedmonomers resulting from step (I) onto the substrate surface thereby forming apolymeric coating on said substrate surface whilst maintaining the acidic and/or basicfunctionality of the monomers. Preferred polymerisable groups are alkenyl groups.Polymeric salt coatings resulting from the above method have excellent barrierproperties and coatings in accordance with the present invention will enhance thehydrophilic, biocompatible, anti-fouling and controlled surface pH applications ofsubstrates such as filtration and separations media.
