Abstract

The physicochemical properties of plasma polymerized films were investigated by means of X-Ray photoelectron spectroscopy (XPS), Fourier Transform infrared spectrophotometry (FTIR), ellipsometry and Water Contact Angle. Three different monomers (acrylic acid, ε-caprolactone and lactic acid) were polymerized in a Plasma Polymerization System for different times (7, 15 and 30 min) and power conditions (80 and 120 W). While plasma polymerized acrylic acid and ε-caprolactone shared a strong similarity with the conventional polymers, lactic acid did not bear any resemblance to the conventional polymer.
