Silane coupling agent having dithiocarbamate group for photografting of sodium styrene sulfonate on glass surface

For a photograft‐polymerization of sodium styrene sulfonate onto a glass surface, glasses were treated with a photosensitive silane coupling agent (N, N‐diethylamino) dithio‐carbamoylpropyl (trimethoxy) silane (DATMS). The characteristics of the glass surfaces were examined by UV and IR spectroscopic methods and the contact‐angle technique. The contact angles of air and n‐octane in water were measured to estimate interfacial energy of the surfaces.
