Combined XPS and contact angle studies of ethylene vinyl acetate and polyvinyl acetate blends

► Surface properties of dip coated blends of EVA-33 with PVAc were investigated. ► Control of surface pattern protrusion size was achieved for PVAc/EVA-33 blends. ► XPS shoved a linear relation between VA content on the surface and in the bulk. ► A good agreement was found between basic surface free energy and oxygen content. ► Deviations from Cassie-Baxter equation were discussed depending on VA content.
