The Ag2 [ HgI4 ] was synthesized by liquid synthesis method using Hg( NO3 ) 2 ,KI and AgNO3 as raw materials. The XRD and IR spectra techniques were taken to characterize expected compound. The morphology of samples was detected by SEM tech-niques. It proved that the Ag2 [ HgI4 ] compound was formed. Then the Ag2 [ HgI4 ] powders were distributed in organic glass to obtain a composite material. The thermochromic properties of the composite material were studied. The composite material behaved good thermochromic performance at 48℃. Theresults will be used for thermochromic application in near future.%以硝酸汞、碘化钾和硝酸银为原料,在室温条件下,用液相法合成了四碘合汞酸银,并利用XRD谱和红外光谱技术对合成的四碘合汞酸银进行表征,证实了目标产物四碘合汞酸银已经形成。用扫描电镜技术观测四碘合汞酸银固体颗粒的形貌。然后采用一定方法,将合成的四碘合汞酸银分散到有机玻璃中,制得到掺有四碘合汞酸银的有机玻璃复合材料,并对该复合材料进行了热致变色的研究,发现该材料热致变色温度为48℃,而且可逆变色性能好,在热致变色方面具有应用的前景。
