Abstract：

Aiming at the inherent hydrophobicity of polyethersulfone (PES) ultrafiltration membranes, which leads to membrane fouling and degradation of separation performance, a convenient and efficient “hydrophilic cross-linked network” strategy has been designed. During the dissolution of PES, 3-aminopropyltrimethoxysilane (APTMS) and polyethylene glycol diglycidyl ether (PEGDGE) were added, and both of them developed into long-chain molecules (A-P) by in situ ring-opening reaction in the casting solution. Subsequent hydrolytic condensation of A-P molecules during phase inversion generated Si-O-Si chemical cross-linking sites triggering the construction of hydrophilic cross-linking networks, and the PES ultrafiltration membrane was prepared. Focusing on the effect of A-P content on the structure and performance of PES membrane, the results showed that with the increase of A-P content, the hydrophilicity of PES membrane was significantly improved, the pore size increased, the percentage of the most available pore size increased. Under the test pressure of 0.1 MPa, the pure water flux was increased by nearly 4 times compared with the original membrane, and the BSA retention rate was increased to 98%.
