article description
Medical-grade polyvinyl chloride was coated by polysaccharides through a novel physicochemical approach. An initial surface activation was performed foremost via diffuse coplanar surface barrier discharge plasma in air at ambient temperature and pressure. Radical graft copolymerization of acrylic acid through grafting-from pathway was directed to render a well-defined brush, and finally chitosan monolayer and chitosan/pectin alternating multilayer were bound onto the functionalized surfaces.
