A method of coating a substrate includes adding ion erosion resistant particles, conductive particles, and a binder to an electrophoretic solution in an electrophoretic deposition apparatus including the substrate and a cathode spaced from the substrate. A current is applied to the substrate and cathode to deposit a first layer coating including the erosion resistant particles, the conductive particles, and the binder onto the substrate. The method further includes adding a low work function material to an electrolyte solution in an electrolytic deposition apparatus including the substrate and a cathode spaced from the substrate. A current is applied to the substrate and the cathode to deposit a second layer coating including the low work function material onto the substrate.

Metal nanoparticle agglomerates may render the surface of an article biocidal toward microorganisms. Articles having a biocidal surface may comprise a coating comprising metal nanoparticle agglomerates adhered via an adhesive to at least a portion of a surface of the article. A coating formulation comprising metal nanoparticle agglomerates may be applied to the surface of an article to accomplish the foregoing.

The present invention relates to silica aerogels with a high to very high loading (55-90% w/w) of encapsulated biocidal and/or biorepellant compounds and very low thermal conductivity and to methods of making and using such aerogels in anti-fouling compositions, which are especially suitable for coatings (marine paints, coatings, sealants, lacquers, wood protection or similar controlled leaching systems) that are naturally exposed to humid conditions and/or water, including sea water, and thus prone to fouling.

A mixture curable to provide a fibre reinforced coating material for protecting a substrate. The mixture comprises a phenolic resin or a polyfurfuryl alcohol resin, a hardener, a thixotropic additive, and fibres.

Articles useful for bedding and other comfort applications include a coated polyurethane foam. The coating includes an elastomeric polymer, a phase change material and ceramic particles. The coating provides desirable haptic properties, including a cool touch feature that creates a sensation of coolness when touched. The invention is also a coating composition for producing such a coating, and a method for producing the coating composition
