Abstract:
Shielding coatings are applied to polymer substrates for selective metallization of the substrates. The shielding coatings include a primer component and a hydrophobic top coat. The primer is first applied to the polymer substrate followed by application of the top coat component. The shielding coating is then selectively etched to form an outline of a desired current pattern. A catalyst is applied to the patterned polymer substrate followed by electroless metal plating in the etched portions. The portions of the polymer substrate which contain the shielding coating inhibit electroless metal plating. The primers contain polyamines and the top coat contains hydrophobic alky organic compounds.

Abstract:
Articles having crosslinked poly(vinyl alcohol) (PVA) and silica nanoparticle multilayer coatings are provided. More specifically, articles including a substrate, and a multilayer coating attached to the substrate are provided. The multilayer coating includes a first crosslinked poly(vinyl alcohol) (PVA) layer and a first silica layer. The first crosslinked PVA layer is an outermost layer of the multilayer coating. The first silica layer comprises a plurality of acid-sintered interconnected silica nanoparticles arranged to form a continuous three-dimensional porous network. The PVA and silica nanoparticle multilayer coatings can be used on a large variety of substrates and tend to be resistant to wet and dry abrasions, scratches, and impacts.
