In comparison with other chemistries, little has been reported on sulfur‐containing plasma polymers; reasons include low volatility or high toxicity of monomers. Here, we report on plasma polymerization of dimethyl sulfoxide, by itself and its co‐polymerization with 1,7‐octadiene to generate S‐containing plasma polymers. Results show dominance of SS, SH, and SC with small percentages of SO and SO 2 . Upon storage in air there were no observable changes to the oxidation states of the S atoms in these plasma polymers, whereas the hydrocarbon component underwent oxidative changes. Methods were studied to oxidize the initial sulfur‐containing surface groups, but approaches such as H 2 O 2 treatment post‐deposition and electrical biasing during deposition did not affect the oxidation states of the incorporated S.
