Abstract
Radio frequency magnetron sputtering of polypropylene (PP) using argon as a working gas was applied in order to prepare organic films. Changes of the structure and morphology of the PP target and sputtered films have been investigated by infrared spectroscopy, AFM and scanning electron microscopy. It has been shown that the sputtered films are hydrocarbon plasma polymers. The increased incorporation of OH groups into the deposited films was found as a consequence of the PP target history.
