Abstract
A method for making transparent continuous zeolite film is provided. First a transparent precursor sol is prepared, and the precursor sol is processed to a specific concentration. The precursor solution is coated on a surface of a substrate which is heated under an ambiance of 120˜250° C. in temperature and a humidity less than saturated humidity. The packing of zeolite nanocrystals in the film converted from coated precursor sol has preferred orientation and the film shows super-hydrophobic property.

A method for producing a transparent zeolite film, comprising:
- A. preparing a precursor sol capable of forming zeolite;
- B. processing the precursor sol to a specific concentration;
- C. coating the precursor sol to a surface of a substrate;
- and
- D. heating the coated substrate under a temperature between about 120° C. and about 250° C., and under a humidity less than a saturated humidity to convert the precursor sol to the transparent zeolite film.
