Abstract:

Fabric supports play an important role of the membrane forming, and have an significant influence on the structure and performance of the membrane. In order to obtain a support with the required structure, asymmetric structured wet-laid nonwoven fabrics containing dense and smooth layer and high-mechanical layer was prepared by using wet-laid process and hot-pressing technology for the systematic investigation on the influence of fiber composition on the structure and properties. The results show that the addition of ultra-fine fibers improves surface smoothness, reduces pore size, and improves the processability of the separation membrane. When the porosity and structural parameters of the support were increased, and the porous structure of polysulfone membranes was accordingly regulated by influencing the phase separation forming process of the separation membrane, with the finger-like pores gradually shorten to circular sponge-like cavity structure. The permeance and bovine serum albumi rejection of the polysulfone membranes were also improved, indicating a new research idea for the separation membrane supports.

Key words: separating membrane, support, wet-laid nonwoven fabric, asymmetric structure, ultra-fine fiber
