Phase Change Materials for Cold Weather Clothing

第一阶段研究论证了制备生物聚合物支载相变材料储存有用能量的可行性。通过用相变材料对服装类聚合物进行化学改性，结果表明，衍生产物可以可逆地储存大量的能量作为热。这些产品被发现在对服装应用具有吸引力的温度下释放热能。结果表明，转变温度可以根据需要进行调节。第二阶段计划在这项研究研究的基础上继续和扩大。拟议的工作包括详细研究聚合物的官能化反应和确定产品的潜热能力的范围。还计划将化学扩展到纤维和合成聚合物。

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.
