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.
