Abstract
Integrally skinned BTDA-TDI/MDI (P84) co-polyimide hollow fibers for pervaporation dehydration of isopropanol were successfully developed, which have superior flux and selectivity towards water. The silicone rubber coating could effectively seal the membrane defects, and improved the selectivity because of its nature of high water permeability. Annealing tremendously increased the separation factor/selectivity especially at 300°C, though densification of selective skin layer and reduction of free volume. The performance of newly developed P84 hollow fibers after heat treatment was superior to most previously reported hollow fibers. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
