采用溶胶-凝胶法成功制备了 SnO2∶F/Si O 2气凝胶复合镀膜玻璃,并采用扫描电子显微镜(SEM)、导热系数仪、红外光谱仪,紫外-可见光谱仪等对镀膜玻璃的微观结构、热导率、辐射率、透光率等进行了表征.结果表明,镀膜玻璃的透过率最高在75％左右；辐射率为0．53,复合镀膜玻璃与FTO 玻璃相比,其热导率从3．615W/(m?K)降低到3．368W/(m?K),所得复合镀膜玻璃兼具低热导性和低辐射性.
SnO2∶F/silica aerogel multilayer coated glass was prepared via sol-gel process.SEM,thermal con-ductivity meter,FT-IR and UV-Vis optical spectrometer were used to characterize the mophology,thermal con-ductivity,low-E performance and transmittance of the coated glass.The results showed that the transmittance of the coated glass was up to 75%,the emittance was 0.53.Compared to FTO glass,the thermal conductivity of multilayer coated glass decreased from 3.615 to 3.368 W/(m??K),indicating that the multilayer coated glass possessed both low thermal conductivity and low emittance properties.
