Abstract: In alternative embodiments, provided are shape stable Phase Change Material (PCMs), which in alternative embodiments, are encapsulated shape stable PCMs. In alternative embodiments, provided are shape stable Phase Change Materials (PCMs) comprising a mixture of: a hydrogenated diene copolymer, an (ethylene-octene) multi-block copolymer, a triblock copolymer, a diblock copolymer, an olefin or a polyolefin block copolymer; a PCM comprising at least one fatty acid or fatty acid derivative; a paraffin; a polyol; a fatty alcohol; and a eutectic or a eutectic mixture. In alternative embodiments, provided are methods for manufacturing the PCMs as provide herein. In alternative embodiments, these PCMs are used in Thermal Energy Storage (TES) systems for thermal management in different applications such as electronics, clothing, building or a building material, automotive, aircraft, medical, food and drug storage, and industrial applications.

Abstract: This invention generally relates to thermoregulation and temperature stabilization, thermal protection and insulation, and nucleating agents. In particular, in alternative embodiments, provided are organic phase change materials comprising diesters and alkanolamides. In alternative embodiments, provided are Phase Change Material (PCMs) compositions comprising diesters and alkanolamides, and methods for making and using them. In alternative embodiments, the Phase Change Material (PCMs) compositions are used for thermal energy management, including energy storage and/or temperature stabilization, in various applications such as building, automotive, packaging, garment and footwear, textiles, fabrics, synthetic fibers, foods, microcapsules and other energy storage systems.
