Gas plasmas are a convenient way of modifying the surface properties of polymers without significantly altering their bulk properties. As such they have been proposed as a means of modifying the surface properties of polymers to enhance the cellular response to the materials for particular applications. XPS has been used to determine both the elemental composition and chemical state functionality of PET and PTFE polymers modified using two different RF plasma systems (Capacitor Plate and Inductive Coil) with nitrogen and ammonia gases. Initial results indicate significant differences in modification of the polymers with the respective treatments.
