摘　　要：以TiO_2为载体制备了TiO_2-Cu[HgI_4]纳米复合材料,利用HRTEM、XRD、DSC、UV-Vis等方法对该材料的结构及其热致变色性能进行了研究。研究表明,TiO2-Cu[HgI4]纳米复合材料具有较好的热致变色性能,随着nTiO_2/nCu[HgI_4]摩尔比值的增大,其可见光吸收性能增强,相变温度也相应升高。TiO2-Cu[HgI4] nanocomposite was synthesized by using TiO2 as carrier. HRTEM, XRD, DSC and UV-Vis wereemployed to characterize the structure and investigate the thermochromic performance of the nanocomposite. Resultsindicate that TiO2-Cu[HgI4] nanocomposite has good thermochromic performance. The visible light absorption isstrengthened with the increase of nTiO2/nCu[HgI4] mole ratio, and the phase transition temperature rises accordingly.
