Abstract: An antimicrobial foam includes an open-cell foam in a foam matrix defining a plurality of interconnected bubbles therein. Silver nanoparticles are suspended within the foam matrix. The foam matrix may be made from polyether polyurethane, polyester polyurethane, polycarbonate, thermoplastic olefin, thermoplastic elastomer, and thermoplastic polyurethane. The silver nanoparticles may have an average size between about 5 and 100 nanometers. The silver nanoparticles may be incorporated into the foam matrix in a concentration of between about 0.01 weight-% and about 0.20 weight-%. A method of manufacture of the foam also is described.

Abstract: Embodiments herein describe a cooling cushion or bedding product and methods of making the same. In some embodiments, the cooling cushion or bedding product comprises a microencapsulated phase change material having a melting point in the range from about ?30° C. to about 55° C. and a foam. In some embodiments, the microencapsulated phase change material is uniformly dispersed within the foam. Embodiments herein also describe a method of making a cooling cushion or bedding product comprising dispersing a microencapsulated phase change material into a polyol to create a polyol-PCM blend and adding an isocyanate to the polyol-PCM blend. Some embodiments describe a method of making a cooling cushion or bedding product comprising pouring polyol, microencapsulated phase change material having a melting point in the range from about ?30° C. to about 55° C. and isocyanate together to form a foaming reaction.
