Atmospheric pressure plasma co-polymerization of ethylene glycol and styrene was applied to produce poly
(ethylene glycol-co-styrene) using a dielectric barrier discharge. The chemical structure of polymerized films was studied
by Fourier-transform infrared spectroscopy which confirms that we obtained copolymerized films with hydroxyl groups
incorporated. Chemical composition of films was studied by X-ray Photoelectron Spectroscopy and oxygen containing
groups (C-O and C=O) were identified. Topography of polymer films was revealed using Atomic Force Microscopy
technique and the film root mean square roughness (Rrms) was found to be 1.6 nm. Surface wettability was analyzed using
water contact angle technique.
