Effect of Annealing and Polymeric Additives on Permeation Properties of Asymmetric Polyacrylonitrile Membranes

  • Published : 2004.05.01

Abstract

Since Loeb and Souriajan first introduced phase inversion method [1], much investigation has been made for understanding the mechanism of formation of asymmetric membranes. Phase inversion is the most extensively used technique for the preparation of asymmetric membranes, which is that cast solution film on a substrate is immersed and is precipitated in water bath.(omitted)
