Plasma treatment of polyacrylonitrile/vinyl acetate films obtained by the extrusion process

This work presents a study of superficial properties of polyacrylonitrile (PAN) films obtained by extrusion process. This innovative material was submitted to microwave plasma treatment generated at low pressure. The contact angle was measured with and without treatment in nitrogen and argon plasma, by the pendant drop technique. The work of adhesion was calculated by the Young–Dupre equation. The surface energy was calculated by the harmonic...
