  • Patent number: 11828060
    Abstract: A method of making an insulated material comprises melting a phase change material to form liquid phase change material, combining the liquid phase change material with an insulating material, and forming a composite insulation material in response to the combining. The insulating material can be a porous material that comprises a plurality of pores, and the liquid phase change material is disposed in the plurality of pores. The phase change material can also be stored in a container and used as layer in an insulation system.
