摘要：在三乙醇胺作用下利用SnCl4和SbCl3共沉淀合成了SnO2:Sb纳米粒子,通过球磨分散得到了纳米SnO2:Sb网络结构的悬浮体系,该悬浮体系形成的玻璃质导电薄膜表面电阻达到107Ω。三乙醇胺提高了SnO2:Sb前驱体胶粒间静电斥力,增大了胶粒分散程度,促进了SnO2:Sb立体网络结构的形成。采用TEM、Zeta电位和XPS分析方法,研究了三乙醇胺与SnO2:Sb前驱体颗粒的相互作用,解释了SnO2:Sb导电网络的形成过程。
SnO_2：Sb nanoparticles were prepared by co-precipitating SnCl_4 and SbCl_3 with triethanolamine.The SnO_2：Sb nanoparticle dispersions with network structure were formed by ball milling,and the surface resistance of thin film coated on glass by this suspension was about 10~7 Ω,which was two orders of magnitude lower than that of non-organics.According to the analysis results of TEM,Zetasizer and XPS,the mechanism model of the interaction between triethanolamine and SnO_2：Sb precursor particles was hypothesized which well interpreted the formation of SnO_2：Sb network.
