By using 30/70 polyethersulfone/NMP ( N-methyl-2-pyrrolidone) solutions as an example, we have determined the role of air-gap distance on nascent fiber morphology, performance, and thermal properties. An increase in air-gap distance results in a hollow fiber with a less layer of fingerlike voids and

The objectives of this work are, fundamentally, to understand hollow fiber membrane formation from an engineering aspect, to develop the governing equations to describe the velocity profile of nascent hollow fiber during formation in the air gap region, and to predict fiber dimension as a function o

The influence of heat-treatment conditions on the morphology and pervaporation performances of aqueous isopropanol (IPA) solution through wet spinning prepared polyacrylonitrile (PAN) hollow fiber membranes were investigated. At heat-treatment temperature higher than 210 โ€ข C, dehydrogenation and cyc
