Microcapsules loaded with n-docosane as phase change material (mPCMs) for thermal energy storage with a phase change transition temperature in the range of 36–45 °C have been employed to impregnate cotton fabrics. Fabrics impregnated with 8 wt % of mPCMs provided 11 °C of temperature buffering effect during heating. On the cooling step, impregnated fabrics demonstrated 6 °C temperature increase for over 100 cycles of switching on/off of the heating source. Similar thermoregulating performance was observed for impregnated fabrics stored for 4 years (1500 days) at room temperature. Temperature buffering effect increased to 14 °C during heating cycle and temperature increase effect reached 9 °C during cooling cycle in the aged fabric composites. Both effects remained stable in aged fabrics for more than 100 heating/cooling cycles. Our study demonstrates high potential use of the microencapsulated n-docosane for thermal management applications, including high-technical textiles, footwear materials, and building thermoregulating covers and paints with high potential for commercial applications.

基于微囊相变材料的长效自主调温织物

载有正二十二烷的微胶囊作为相变材料 (mPCM) 用于热能存储，相变转变温度在 36-45°C 范围内，已被用于浸渍棉织物。浸渍有 8 wt% mPCM 的织物在加热期间提供 11 °C 的温度缓冲效果。在冷却步骤中，浸渍织物在 100 多次打开/关闭热源的循环中温度升高了 6°C。对于在室温下储存 4 年（1500 天）的浸渍织物，观察到类似的温度调节性能。在老化的织物复合材料中，加热循环期间温度缓冲效应增加至 14°C，冷却循环期间温度增加效应达到 9°C。在 100 多个加热/冷却循环中，两种效果在老化织物中保持稳定。
