In this study, a series of polycarbonate/polyacrylonitrile (PC/PAN) composite membrane has been successfully fabricated by vapor-induced phase separation and in-situ casting process. The effect of the casting solution concentration on the membrane morphology was investigated. The morphology of the P

PSf hollow fiber membranes were fabricated by a dry/wet spinning process. The morphology and separation performances of the fibers were found to be strongly affected by air gap and ambient humidity. Macrovoids in the membranes disappeared, reappeared, and redisappeared with increasing air gap. The a
