Thermally conductive nanomaterial coatings on flexible foam or fabrics

A flexible cellular foam product comprising:

• a flexible foam substrate having a first zone and a second zone, the first zone having a first surface and a second zone having a second surface;
• and
• a first coating layer overlaying at least a portion of the first surface,
• a second coating layer overlaying at least a portion of the second surface,
• wherein at least one of the first and second coating layers comprising a binder and a highly thermally conductive nanomaterial, the binder binding the highly thermally conductive nanomaterial of the coating layer to the flexible foam substrate, and the first coating layer has a greater heat conductivity than the second coating layer.

A product comprising:

• a substrate selected from a group consisting of a fabric, a flexible slabstock foam, flexible molded foam, and a latex foam, the substrate having at least one surface;
• and
• a coating layer comprising a highly thermally conductive nanomaterial on the at least one surface of the substrate, and a binder on at least one surface of the flexible foam or fabric substrate, the binder binding the highly thermally conductive nanomaterial to the at least one surface,
• wherein the binder is selected from a group consisting of acrylic polymer emulsions produced from a monomer selected from a group consisting of ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, acrylic acid, methyl acrylate, and combinations thereof, polyvinylidene chloride latex, styrene-butadiene latex, carboxylated acrylonitrile butadiene rubber, carboxylated butadiene copolymer rubber, styrene-acrylic emulsion polymers including resin supported emulsions, vinyl-acetate based polymers such as vinyl acetate ethylene copolymers and vinyl acrylic latex, nitrile latex elastomers, nitrile-butadiene elastomers, polybutadiene elastomers produced from 1,3-butadiene elastomers, dicyclopentadiene-based elastomers, ethylene propylene dicyclopentadiene-based elastomers, neoprene binder, natural rubber binder, water-based polyurethane elastomers, starch/dextrin-based binders, protein/casein-based binders, silicone-based binders, and combinations thereof, and
• the highly thermally conductive nanomaterial being present only on the at least one surface of the flexible foam substrate.
