摘要:
A polymeric hypernucleophilic catalyst is effective for hydrolytic destruction of chemical threat agents under mild conditions, e.g., near neutral pH and at ambient temperatures. The polymeric hypernucleophilic catalysts are particularly useful to affect rapid destruction of chemical threat agents on sensitive surfaces such as paint, metal, rubber, plastic, fabric, wood, and skin. Catalyst formulations such as creams, lotions, sprays, foams, powders, or gels, and articles such as filters, wipes, membranes, yarns, fabrics, and articles of clothing, may be used for detoxification of or prophylactic protection against chemical threat agents.

摘要:
An electronic device comprising a substrate having a component-side surface and a moisture protection film covering the component-side surface. The moisture protection film includes a first water layer bonded to component-side surface that is an activated surface, wherein the activated surface has a lower water contact angle than the substrate surface before the surface activation. The film includes a first graphed layer of a plasma-reacted first set of precursor molecules graphed to the first water layer, wherein the first water layer forms a first bonding link between the substrate surface and the reacted first set precursor molecules. The film includes a second water layer bonded to the first graphed layer. The film includes a second graphed layer of a plasma-reacted second set of precursor molecules graphed to the second water layer, wherein the second water layer forms a second bonding link between the second water layer and the reacted second set of precursor molecules.
摘要:
A film deposition process comprising exposing a surface of a substrate to a first plasma treatment having plasma reactants in a plasma chamber to form an activated substrate surface. The activated surface has a lower water contact angle than the substrate surface before the surface activating. The process comprises introducing water vapor into the plasma chamber to form a water layer on the activated surface. The process comprises introducing pre-cursors molecules into the plasma chamber in the presence of a second plasma to graft a layer of reacted pre-cursor molecules on the water layer.
摘要:
A method of manufacturing a polymeric object that comprises providing a polymeric substrate, and exposing said substrate to a first stage that includes an initial plasma reactant so as to reduce a water contact angle of a surface of the substrate, and, wherein the initial plasma treatment activates the surface to a grafting reaction, The method further includes exposing the activated substrate surface to a second stage that includes a second plasma reactant to thereby deposit a grafted material on the activated substrate surface to form a grafted surface.
