Abstract
The present invention relates to a method of post-treating a zeolite membrane, comprising treating a defective zeolite membrane with a chemical material such as a dye molecule, which has a size larger than that of the pores of the zeolite membranes and smaller than defects in the membrane, thereby healing the defects in the membrane. The post-treatment method performs post-treatment of the zeolite membrane under mild conditions (room temperature and normal pressure), thereby selectively healing the defects in the zeolite membrane and improving the performance of the zeolite membrane. In addition, the method may provide a high-performance membrane having a high separation factor, particularly under dry conditions.
