Abstract：

Polyimide has excellent comprehensive properties. In this paper, a soluble polyimide membrane material was prepared based on the design of diamine monomer. The polyimide nanofiltration membrane was successfully prepared by phase separation, which is a simple way. The molecular structure of the polyimide membrane material was verified by infrared spectroscopy, and the membrane material show sound solvent resistance, but it can be dissolved in the solvent of NMP. The prepared nanofiltration membrane has a typical asymmetric structure, which can achieve the separation of monovalent and bivalent salt effectively. The retention rate of RB dyes with molecular weight of 1017 was higher than 92%, and that of spiramycin with molecular weight of 843 was higher than 92%. With the increase of molecular weight of PEG, the rejection rate increased. For various separation aims, the flux was between 10-34 L/(m2·h)
