Abstract
The water-casting method is one of the most important techniques for the preparation of pinhole-free ultrathin film for air separation. Strong interest exists in the optimizations of preparing routes of the ultrathin film and of the fabrication of the ultrathin-film composite membranes with a variety of polymers. A number of water-casting solvents with high spreadability over water are offered in the present review. Progress made in the inconsecutive and continuous preparations of ultra-thin films is reviewed in detail. The oxygen perms electivity, air separation performance, and the stability of ultrathin-film composite membranes are discussed with a detailed citation of references. This review also compares the performances through ultrathin-film composite membranes fabricated by the water-casting method with other methods.
