Abstract: Catalyst-enhanced chemical vapour deposition of Pt and Pd-Pt bilayer films on polysulfone using N2 and O2 as the carrier gas was investigated. Only Pt was deposited when the mixture of complexes Pt(COD)Me2 and Pd(hfac)2 was used as precursors in the same chamber. Sequential deposition of two metals formed Pd-Pt bilayer films. The particle size of Pd and Pt on polysulfone is 15-30 nm, and the thickness of the bilayer is 120-180 nm.

Key words: catalyst-enhanced chemical vapor deposition, polysulfone, platinum film, palladium-platinum bilayer film
