Investigated the effects of the operating parameters such as the heating temperature on substrate, the rates of the main air, auxiliary air flow and deposition time, could prepared the good quality nanocomposite films. The crystalline, surface morphology, and chemical composition of prepared samples would performed by the instruments of XRD, FT-IR, BET, TGA, SEM, TEM ,AFM and Constant Angle Meter. The result showed that zeolite nanocomposite thin films deposited by our system is success and also remove the template agents simultaneously .Compared with spin-coating method ,need to remove the template agents under high-temperature calcinations and therefore difficult to avoid the film cracks. Many researches hoped to develop Silicalite-1 membrane as low-k materials as it has good mechanical strength and high porosity more than traditional silicon material. However, the adhesion and hydrophobicity far worse compared of colloids such as macromolecules, the problem mentioned have to effectively solved in order to the commercialize stage. Based on the above fabricating, our zeolite thin films having higher adhesion and hydrophobicity and good flatness, also owned a low dielectric constant (k= 2.17), it shows more potential commerical development is to be expected.
