Coatings from plasma

Primary interest was in the barrier properties obtained from plasma organo-silicones and from inorganic "SIN" coatings. Spectral grade HMDSO was used in the former case, while mixtures of SiH and NH were used to produce the SIN structures. The substrate in much or the work was DuPont Kapton type H polylmide film, 51 pm thick. Substrate temperatures extended to 450 C, as described earlier (6). The thickness of plasma-polymer deposits was about 0.5 pm. Moisture permeation was evaluated by the routine of ASTME-96-53 T (water vapor transmission of materials in sheet form). Additional, more precise data, were obtained with both a Dohrmann Envirotech Polymer Permeation Analyser, modified as previously described (6), and a Mocon "Permatran W" moisture permeation apparatus.

ESR signals [7] observed with LCVD-coated glass rods are shown in Figures 6.5, and 6.6. By removing plasma polymer coating from the surface of a glass rod, it is possible to quantitatively examine both the free spins in the plasma... 

Figure 31.30 Scanned images of Prohesion salt spray-tested A1 panels coated with nonchromated primers prepared in a flow or closed reactor system without using anode assembly Primer X could not be removed from plasma-treated [2P] and [7P] surface due to the strong adhesion.

The effects of the composite parameter WjFM on the friction coefficient of the contact lens coated by methane plasma polymer at a fixed coating thickness 31.2nm are shown in Figure 35.3. The friction coefficient, which is the tangential force divided by the normal force, was calculated from the sliding angle of a contact lens placed on a glass plate that was coated with plasma polymer of tetrafluoroethylene (TFE). The friction coefficient of the methane plasma polymerized contact lens is independent of WjFM in the range 2.6-29.1 GJ/kg.

Direct detection of a cytokine protein, recombinant human interferon-y, using an IBIS SPR sensor is presented in [60]. Several types of sensor chip coatings, including self-assembled monolayers and hydrogel-derivatized SAMs, were characterized in terms of their ability to resist non-specific adsorption from plasma. The best results with respect to plasma adsorption and surface regenerability were obtained with antibodies immobilized on the dextran-modified 11-mercaptoimdecanoic acid SAM. The detection limit for detection of human interferon-y in 1 100 diluted plasma was established at 250ngmL . ...
