摘要

采用均相共辐照方法，将聚乙烯基吡咯烷酮（PVP）接枝到聚醚砜（PES）的分子链上，制备改性的制膜材料（PES-g-PVP），并采用非溶剂致相转换法制备PES滤膜以及PES-g-PVP改性滤膜。研究了单体浓度和吸收剂量等因素对改性膜材料接枝率的影响。结果表明，当单体浓度低于12%、吸收剂量低于35 kGy时，提高单体浓度和吸收剂量，均能有效提升产物的接枝率。傅里叶红外光谱图证实了接枝反应的有效进行。扫描电子显微镜照片发现，不同于PES超滤膜的“指状孔”，PES-g-PVP膜呈现一种“海绵状孔”型的断面结构。相比PES超滤膜，接枝率为8.42%的PES-g-PVP超滤膜的接触角下降12.1%，说明改性后膜材料的亲水性得到有效提高；同时，其对牛血清白蛋白的截留率保持在90%以上，且膜的纯水通量提高了4.9倍，说明接枝后膜材料的抗污染性能得到有效提升。

Abstract

Polymerization was performed in a homogenous phase using N-methylpyrrolidone as the solvent. Pristine polyethersulfone (PES) and PES-grafted poly(N-vinylpyrrolidone) (PES-g-PVP) with different degrees of grafting (DGs) were then cast into membranes via phase inversion methodology. Crucial parameters affecting the graft copolymerization, such as the monomer concentration and absorbed dose, were studied. The results showed that increasing the monomer concentration and absorbed dose both served to improve the DG of the copolymer for monomer concentrations and absorbed dose less than 12% and 35 kGy, respectively. The presence of grafted chains was confirmed by Fourier-transform infrared spectroscopy. Scanning electron microscopy images showed that unlike the pristine PES membrane, the modified PES-g-PVP membrane possessed a "sponge-like" cross section. The contact angle of the PES-g-PVP membranes with a DG of 8.42% was lower than that of the pristine PES membrane by 12.1%, which indicated an improvement of the hydrophilic property of the membrane after grafting PVP onto PES molecular chains. The water flux of the PES-g-PVP membrane with a DG of 8.42% increased by a factor of approximately 4.9 compared with that of the pristine PES membrane, while its bovine serum albumin rejection rate was greater than 90%, indicating the improved antifouling properties of grafted PES-g-PVP membranes.
