智能调光材料透光率研究

Study on Transmittance of Intelligent Light-Control Material

研究了一种调光材料的配方优化及其作用效果.优化配比溶液的转变温度可以控制在24℃左右,接近人居舒适温度.该材料在低于24℃时透光率较高,可达92%,在高于24℃时的透光率则随温度的升高逐渐下降,最低透光率仅为2%,且溶液在从高温降低到转变温度点以下,溶液的透光率又恢复,具有可逆性.同时借助紫外可见分光光度计和模拟实验分别从理论和实践上表明了该种智能调光材料的可应用性,为建筑物智能降温提供了可能性.

A kind of light-control material was studied and its effect was tested in the lab. The result shows that the critical temperature of solution can be controlled at about 24℃, which approaches the comfortable living temperature for mankind. This solution＇ s transmittance can reach 92% below 24 ℃. When temperature is above 24 ℃, the transmittance will decline with the rising of temperature, and the lowest transmittance is only 2 %. The applicability of the light-control material is theoretically and practically confined through spectrum scanner and simulative experimentation. This material＇ s aplication paves a new way for the intelligent material, which has a promising prospect.
