摘要： An asymmetric support membrane can be prepared by using a phase separation method. The method includes immersing a polymer solvent solution into water. The polymer solution is made by dissolving 15 to 35% by weight of the polymer into a solvent that lets the polymer solution become a gel at a temperature of 0 to 50° C. The solution is then allowed to gel and brought into a final membrane form in water for phase separation and formation of the asymmetric support membrane. The polymer may be poly(vinyl chloride), polyethersulfone, polyetherimide and polyamic(methylester). The solvent is &ggr;-butyrolactone alone as a major solvent or is a mixed solvent with N-methyl-2-pyrrolidone as a cosolvent. The asymmetric support membrane is a porous support membrane of a sponge form having open pores that are connected to one another with a narrow pore size distribution. Thus, the asymmetric support membrane has an improved permeance and mechanical strength. Further, because it has a narrow pore size distribution, a coating process can be optimized with a material having high selectivity. Therefore, the composite membranes having improved selectivity can be easily produced by the present invention.
