Abstract:	本實驗將熱致變色材料四氯銅雙二乙基銨鹽依重量百分濃度0.2wt%添加於聚乙烯醇水溶液(8wt%)並依重量百分濃度(0.1wt%、0.15wt%、0.2wt%)添加二氧化鈦製成薄膜，在分別將薄膜照射UV/Vis光譜分析儀和分光分析儀，得到的結果為熱致變色聚乙烯醇添加二氧化鈦薄膜具有吸收400nm-200nm紫外線的功效，而隨溫度的升高會使吸收值上升，透光值下降。 This study was thermochromic materials[(CH3CH2)2NH2]2[CuCl4], according to the weight percentage of fixed concentrations 0.2% adding polyvinyl alcohol (PVA) solution (8%) doped Fe/TiO_2 made of film, and then the film were at the room temperature and heated to 60℃ UV/Vis 200~800nm light absorption and light transmittance values were measured for analysis.The results obtained for the concentration and temperature increases, the [(CH_3CH_2)_2NH_2]_2[CuCl_4] doped Fe/TiO_2 absorption value of polyvinyl alcohol PVA films increased transmittance decreased, [(CH_3CH_2)_2NH_2]_2[CuCl_4] doped Fe/TiO_2 absorption of polyvinyl alcohol (PVA) films value of 200~400nm.
