Abstract
A method for producing polymer coatings by surface initiated polymerization from a plasma deposited coating is provided. The modification of surfaces by polymer attachment is a versatile and efficient means of controlling interfacial properties, such as surface energy (i.e. wetting behavior), permeability, bio-activity, and chemical reactivity. The present invention provides a method whereby a plasma deposited coating is applied to a substrate and the polymer coating formed by surface initiated polymerization is formed on the coating rather than the substrate itself. This means that the growth of the polymer using the grafting from procedure can be performed efficiently and independently of the substrate from.
