| Abstract: | This paper is concerned with the relationship among such factors as species and contents of additives, polyacrylonitrile (PAN) content in PAN cast solutions, temperature of solutions, cellulose (Cell) content in PAN-Cell blended solution, etc. and the morphological structure of the membrane, microporous radius, porousity, rejection as well as water flux of the membrane. It is concluded that these factors have obvious influence on the structure and the performance of the membrane, which can be improved within a wide range by changing thermodynamical conditions of cast solutions. On this basis a series of useful membranes applied in many fields can be manufactured. |
