摘要 以二苯甲酮为光敏剂,通过紫外光辐照引发将苯乙烯磺酸钠接枝到聚丙烯中空纤维膜表面。考察了苯乙烯磺酸钠单体质量分数、光敏剂质量分数对接枝率的影响。利用红外光谱和扫描电子显微镜对接枝中空纤维膜的表面化学组成和形貌结构进行表征,通过水接触角和中空纤维膜的水通量研究接枝前后中空纤维膜的亲水性。结果表明,当接枝率为13.3%时,膜的水接触角由原膜的110°减小至46°;当接枝率为9.0%时,水通量增加到102 L/(m2·h),亲水性得到了显著提升。

Abstract: A novel kind of hollow fiber membrane is prepared through grafting sodium p-styrene sulfonate onto the surface of polypropylene hollow fiber membrane,which is initiated by ultraviolet irradiation using benzophenone as photosensitizer.The influences of the concentrations of sodium p-styrene sulfonate monomer and photosensitizer on the grafting degree are studied.Attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FT-IR) and scanning electron microscopy (SEM) are used to characterize the surface chemical compositions and morphologies of both the original and grafted polypropylene hollow fiber membrane.The measurement methods of water contact angle and permeation flux of hollow fiber membrane are used to characterize the hydrophilic changes of hollow fiber membrane surface.The water contact angle of grafted polypropylene hollow fiber membrane decreases to 46° from 110° of non-grafted membrane when the grafting degree is 13.3%.The permeation flux of grated membrane increases to 102 L/(m2·h) when the grafting degree is 9%.The hydrophilicity of polypropylene hollow fiber membrane is improved dramatically by grafting.
Key words:  polypropylene hollow fiber membrane    UV-irradiation grafting    grafting degree    hydrophilicity
