    • Gel including a phase-change material and a gelling agent. In one embodiment, the phase-change material may be n-tetradecane, and the gelling agent may be a styrene-ethylene-butylene-styrene (SEBS) triblock copolymer. In particular, the SEBS copolymer may be a high molecular weight SEBS copolymer with a styrene:rubber ratio of about 30:70 to 33:67% by weight. The SEBS copolymer may constitute up to about 10%, by weight, of the gel, preferably less than 6%, by weight, of the gel, with n-tetradecane constituting the remainder. To form the gel, the phase-change material and the gelling agent are mixed together at an elevated temperature relative to room temperature to partially, but not completely, dissolve the gelling agent, i.e., a homogeneous solution is not formed. The mixture is then allowed to cool to room temperature. The invention is also directed at a method of preparing the gel and a thermal exchange implement including the gel.
    • 凝胶包括相变材料和胶凝剂。 在一个实施方案中,相变材料可以是正十四烷,并且胶凝剂可以是苯乙烯 - 乙烯 - 丁烯 - 苯乙烯(SEBS)三嵌段共聚物。 特别地,SEBS共聚物可以是苯乙烯:橡胶比为约30:70至33:67重量%的高分子量SEBS共聚物。 所述SEBS共聚物可以构成至多约10重量%的凝胶,优选小于6重量%的凝胶,其中正十四烷构成其余部分。 为了形成凝胶,相变材料和胶凝剂在相对于室温的升高的温度下混合在一起,部分但不完全溶解胶凝剂,即不形成均匀的溶液。 然后将混合物冷却至室温。 本发明还涉及制备凝胶的方法和包含该凝胶的热交换工具。
