| Abstract: | AZO nanoparticles were prepared by sol-gel method,and treated with silane coupling agent.Their PVB composite films were prepared by solution blending.The properties of AZO powders,modified AZO powders and PVB/AZO films were characterized by TG-DSC,XRD,TEM,laser particle analyzer,UV-Vis spectroscopy and UV-Vis-NIR spectroscopy.The influence of the aluminum doping concentration on the crystallization of AZO powders and UV-vis-NIR light absorption properties of PVB/AZO films were investigated.The results show that the crystallization properties of AZO powders were becoming worse with the increaseed aluminum doping concentration.The PVB/AZO composite film gives the highest UV transmittance and lowest NIR transmittance at an aluminum doping ratio of 2%. |
