Abstract: Methods of making a thermoset thermal energy gels, such as one having a radiation cured polymeric network, are disclosed. The methods include providing a hydrophobic PCM in its liquid state, adding a polybutadiene urethane acrylate oligomer and a mono-functional or di-functional crosslinker soluble in the hydrophobic PCM to the hydrophobic PCM while maintaining the liquid state of the hydrophobic phase change material to form a liquid homogenous mixture, then adding a photoinitiator, which is soluble in the hydrophobic PCM, with mixing to form a final mixture. Next, curing the final mixture occurs by exposure to radiation to form the thermoset thermal energy gel.

Abstract: Non-flammable structures are disclosed that have a substrate and a layer applied to the substrate that includes a phase change material that is flammable. The layer includes a binder having mixed therein about 50% to about 90% by weight of a microencapsulated phase change material and about 0.5% to about 10% by weight of an inorganic flame retardant. The inorganic flame retardant has a volume that increases upon exposure to heat or a flame. The binder is selected from the group consisting of a polyurethane, a styrene acrylic copolymer, a styrene butadiene copolymer, acrylic and combinations thereof.

Abstract: Microcapsules are disclosed that have a core composition encapsulated within a polymer wall, and an inorganic shell connected to an exterior surface of the polymer wall by a surfactant. The inorganic shell has a cation attracted to the surfactant and an anion or anion equivalent chemically bonded to the cation to form the shell or has the metal portion of a metal-containing compound attracted to the surfactant to form the shell. The shell may comprise a Ca, Mg, or Ag metal compound. The shell may be a graphene oxide-metal compound.

Abstract: Microcapsules are described that include a hydrophobic core material within an acrylic polymeric shell that was polymerized from a monomeric blend that includes a mono-functional acrylic monomer as less than 25% by weight of the monomeric blend and a hyperbranched polyester acrylic oligomer as the balance of the monomeric blend, and methods of making the same. The methods include a two-stage polymerization process where the monomeric blend is polymerized with an azo-initiator in a first stage polymerization reaction and is subsequently further polymerized with a water soluble initiator in a second stage polymerization reaction.
