Surface properties of plasma-modified poly(1-butene)

Abstract

Surface properties of poly(1-butene) films has been modified by a radio frequency plasma treatment. To minimize degradation and ageing effects it is necessary adjusted the gas composition and the plasma conditions on the polymer type. For this purpose plasma containing five various gasses or their mixtures: air, argon, argon then allylamine, argon wearing ammonia and argon with octafluorocyclobutane, were used. Changes in the surface hydrophilicity, roughness and the chemical composition of modified poly(1-butene) films were investigated by contact angle measurements, atomic force microscopy and X-ray photoelectron spectroscopy. All types of plasma treatment expect fluorocarbon plasma cause increase of polar functional groups on the surfaces and their hydrophilicity. On the other hand, fluorocarbon plasmas cause increase of contact angle and hydrophobicity.
