Abstract

The preparation of thin film coatings with sulfonate and sulfate groups by plasma techniques is not straightforward due to limited volatility of suitable process vapours. We report a combination of plasma polymerisation and plasma treatment, treating heptylamine (HA-SO2) and 1, 7-octadiene (OD-SO2) plasma polymers with sulfur dioxide plasma. HA-SO 2 and OD-SO2 plasma polymer surfaces exhibited different compositions with the latter showing almost twice the amount of sulfur, as well as polysulfonate. Ageing of HA-SO2 plasma polymer surfaces in air or saline solution led to the disappearance of oligomers containing sulfonate and sulfate. Angle-dependent XPS analysis of HA-SO2 plasma polymers suggested that sulfur containing groups reptated into the plasma polymer upon storage after preparation.
