Thin polymeric films were deposited from siloxane plasma on the surface of polyethylene. The surface composition of the films was measured by X‐ray photoelectron spectroscopy (XPS) and the permeability to O 2 by an analytic gas permeability fractometer. No significant improvement of barrier to O 2 was observed with 200 nm‐thick coatings. When the siloxane layer was subjected to a further O 2 plasma treatment, a threefold decrease of permeability to oxygen was recorded. Results are discussed on the light of the effect of the O 2 plasma on the siloxane backbone. © 1993 John Wiley & Sons, Inc.
