    • Combinations of gelatinous elastomer containing one or more phase change materials, known as “phase change gel”, and polyurethane foam may be made by introducing at least partially cured phase change gel particles comprising plasticized triblock copolymer resin and/or diblock copolymer resin and one or more phase change materials, into a mixture of polyurethane foam-forming components including a polyol and an isocyanate. The phase change gel can be crosslinked to form a cured gelatinous gel, which is then reduced in size before introduction. After the foam-forming components polymerize to make polyurethane foam, the phase change gel particles are discrete visible particles dispersed throughout the foam. The polyurethane reaction is exothermic and can generate sufficient temperature to at least partially melt the styrene-portion of the triblock copolymer resin thereby extending the crosslinking. The combination of phase change gel and polyurethane foam increases the heat storage capacity and thermal conductivity of the foam.
    • 含有一种或多种相变材料的凝胶状弹性体(称为“相变凝胶”)和聚氨酯泡沫的组合可以通过引入至少部分固化的相变凝胶颗粒,包括增塑的三嵌段共聚物树脂和/或二嵌段共聚物树脂和一种或多种 更多的相变材料成为包括多元醇和异氰酸酯的聚氨酯泡沫形成组分的混合物。 相变凝胶可以交联以形成固化的凝胶状凝胶,然后在引入之前尺寸减小。 在泡沫形成组分聚合以制备聚氨酯泡沫之后,相变凝胶颗粒是分散在整个泡沫中的离散可见颗粒。 聚氨酯反应是放热的并且可以产生足够的温度以至少部分地熔化三嵌段共聚物树脂的苯乙烯部分,从而延长交联。 相变凝胶和聚氨酯泡沫的组合增加了泡沫的储热能力和导热性。
