Poly (vinyl alcohol) (PVA) solution containing the glutaraldehyde (GA) as a crosslinking agent was coated onto the polyacrylonitrile (PAN) hollow fiber membrane as the supporter. Pervaporation experiments were carried out to characterize the prepared PVA/PAN composite membrane for water-isopropyl alcohol mixture. The flux and separation factor were measured at 30, 50, 90℃ for the feed mixture of aqueous 85 wt% IPA solution with varying the reaction temperature and composition of coating solutions. Typically the flux showed 1,870 g/m2 ⋅hr at 90℃ feed mixture and the coating concentration of 3.5 wt% and the highest separation factor of 804 was obtained at 30℃ feed mixture and the coating oncentrationof 7 wt% as well.
