Phase Change Materials for Cold Weather Clothing

第一阶段研究证明了制备 生物聚合物支撑的相变材料， 大量的能量。 通过化学改性的布型 聚合物与相变材料，它表明， 衍生产品可以可逆地储存大量的 能量转化为热量。 这些产品被发现释放热量 在对衣服有吸引力的温度下的能量 应用程序. 发现转变温度 可以根据需要进行调整。 第二阶段计划继续并扩大了这项研究 study. 拟议的工作包括详细研究聚合物 官能化反应和确定的范围， 产品的潜热能力。 延长 化学纤维和合成聚合物也计划。

Phase I research demonstrated the feasibility of preparing biopolymer supported phase change materials to store useful quantities of energy. By chemical modification of clothing-type polymers with phase change materials, it was shown that the derivatized products can reversibly store significant quantities of energy as heat. The products were found to release the heat energy at temperatures that are attractive for a clothing application. It was found that the temperature of transition could be adjusted as desired. The Phase II program continues and expands upon this research study. The proposed work includes a detailed study of the polymer functionalization reactions and a determination of the scope of the latent heat capabilities of the products. Extension of the chemistry to fibers and synthetic polymers is also planned.
