Abstract

Thin films were produced by plasma enhanced chemical vapor deposition from propanol-chloroform-argon mixtures. The main system parameter studied was the percentage of chloroform in the chamber feed, C-Cl Plasma polymers doped with chlorine were produced at deposition rates of up to 110 nm min(-1). As revealed by infrared and X-ray photoelectron spectroscopy, the films consisted of a hydrogenated carbon matrix with a carbon content of at least 80 at.%, and a roughly constant oxygen content of about 12 at.%. A maximum chlorine content of similar to 8 at.% was obtained. The surface contact angle of the films was around 75, and was reduced slightly at greater chlorine contents. Optical properties were obtained from ultraviolet-visible-near infrared spectroscopic data. While the refractive index of the films was around 1.56 independently of C-Cl, the chlorinated films showed a distinct optical gap of similar to 2.5 eV compared to similar to 1.9 eV for the unchlorinated film.
