The deposition of thin polymeric films from plasma (PFP) is a topic of considerable importance, both from a fundamental and an applied point of view. The applications of PFP film deposition span several different fields, such as corrosion protection, permeability, and biomedical materials. The effect of the power discharge on the surface properties of thin films deposited from hydroxyethylmethacrylate plasma was evaluated by X-ray photoelectron spectroscopy and contact angle measurement. Surface energetics parameters were measured by model acidic or basic test liquids and discussed according to the theories of acid-base or electron donor/electron acceptor interfacial interactions. Results show that the power discharge has a marked effect on the acid-base properties of the plasma-deposited films and, as a consequence, on the interactions of the latter with the surrounding environment.
