Abstract

Differential scanning calorimetric melting endotherms of wet and half‐dried cellulose acetate membranes and salt distribution coefficients were studied to clarify the states of water in membranes. We have suggested that (a) there are four states of water in cellulose acetate membranes; (b) these states of water are those of completely free water, free water very weakly interacting with polymer, bound water which can contain salts, and bound water which rejects salts; (c) the semipermeability of membranes depends on the ratio of four states of water in membranes.

In the present work, N,N-dimethylformamide was chosen as a cosolvent of cellulose acetate (CA) and polyacrylonitrile (PAN). The blend solution showed appropriate viscosity, good membrane-forming property and relative stability.
