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.
