The influence of different assembled condition such as assembly method, concentration of zirconium source and pH value on the effectiveness of assembly were evaluated via DSC-TG, FT-IR, Uv-vis and SAXRD et al. It showed that the assembly effectivness of uncalcined 3 Si/Zr_10# sample was best.c The optical characteristic, which including light-conduction in infrared band and polarity in visible band, of dip-coating film and membrane assembled zirconia after processing parameters of assembly optimized were observed via FT-IR and Uv-vis. The polarity was characterized by polarizing angle through calculation from light-transmittance, light-reflectance and fresnel coefficient. qualitative analysis showed that the polarity of Si/Zr_10 # dip-coating film assembled was best.d Adopting zirconium oxychloride as zirconium source, CTAB as template, employing different CTAB adding sequence, two mesoporous zirconia samples were prepared. The template effect of two samples was discussed. It showed that the effect of the sample which CTAB adding sequence was same as mesoporous silica film was better. The light-conduction in infrared band of these samples was also studied, which offered comparison to the polarity of zirconium dioxide assembled within mesopore.

结果显示：组装条件优化后的uncalcined 3 Si/Zr_10#厚膜样组装效果最好，其组装液对应的pH值最利于该锆源离子模板交换组装； c选用FT-IR、Uv-vis对组装条件优化后纳米氧化锆/介孔氧化硅厚膜、纳米氧化锆/介孔氧化硅薄膜包括红外导光性、可见光区内的偏光性在内的光学特性进行了分析，其中偏光性以膜层透光性、反光性及菲涅耳系数计算出的偏振角即布儒斯特角表征，定性分析显示，Si/Zr_10#ZrO_2/介孔氧化硅厚膜偏光性最好； d以氧氯化锆ZrOCl_2·8H_2O为锆源，CTAB为模板剂，采用不同的模板剂加入顺序，探索性地制备两介孔氧化锆样，分析了两介孔氧化锆样的模板效果，得出模板剂加入顺序同介孔氧化硅薄膜时介孔氧化锆样的模板效果较好，并分析了所得样品的导光性，为锆氧粒子引起的附加光学特性分析提供了参考和对比。
