Notizen: Highly wettable films were prepared by plasma-polymerization from ethylene oxide. The surface energy of the formed films is 65.6 dyn/cm, and the contact-angle of water on the films is 12 degrees. The formation of highly wettable films is limited to the plasma-polymerization conducted at low W/FM values of below 200 MJ/kg. Analyses by infrared spectroscopy and ESCA show that the formed films contain much oxygen residues such as C—O, C—O, and C(O)—O— groups. Such polar groups would contribute high wettability of the plasma-films from ethylene oxide.

Notizen: Polymeric films were deposited on Al2O3 ceramic substrates by plasma deposition from trimethylsilyldimethylamine (TMSDMA) and bis(dimethylamino)methylvinylsilane (BDMAMVS), and their capacitance-relative humidity characteristics investigated. Films doped with methylbromide showed a linear dependence of log(capacitance) with relative humidity over the range 20-90% suggesting application on a moisture sensor device. Hysterisis effects were negligible and the response time was within 1 min.
