英文摘要：

The b oriented TS-1 films on α-A12O3 substrates were synthesized by using in situ crystallization by the inducing effect of the chitosan thin film. The synthesized TS-1 films were characterized with XRD and SEM. The functional groups on the chitosan film surface and the interactions between the chitosan film and synthesis solution were described by using diffuse-reflectance FT IR and contact angle measurements. It was shown that the b oriented TS-1 film could be synthesized with the help of the chitosan thin film, whereas the randomly oriented TS 1 film was obtained on the α-Al2O3 substrate without chitosan induction. The XRD patterns of the synthesized films revealed that the crystals possessed TS-1 zeolite structure. The diffuse reflectance FT-IR spectrum and contact angle measurements exhibited that the functional groups were abundant on the surface of the chitosan thin film, which could attract organic and inorganic compounds. Therefore, a transitional layer could be formed on the chitosan film, with nucleation and crystal growth to sheet shaped TS-1 crystal grains, eventually leading to the formation of the multilayer b oriented TS-1 film.
