摘要：以过硫酸钾(K_2S_2O_8)为氧化剂、γ-氨丙基三乙氧基硅烷(KH550)为偶联剂、氨基硅油乳液(ASOE)为接枝改性液,对聚砜(PSF)膜进行疏水改性研究。考察了KH550溶液的质量分数、处理温度、处理时间和ASOE的接枝时间、接枝温度对膜疏水性的影响。采用全反射-傅里叶红外光谱(ATR-FTIR)对接枝前后的膜进行表征,采用扫描电子显微镜(SEM)观察改性前后膜的表面形貌变化。结果表明,疏水性基团被接枝到PSF膜表面,改性后PSF膜的水接触角从87°提高到116°,疏水性得到提高。
Polysulfone（PSF）membrane was modified using persulfate（K_2S_2O_8）as oxidizer,γ-aminopropyltriethoxysilane（KH550）as coupling agent,and amino silicone oil emulsion（ASOE）as grafting liquid.Factors affecting the membrane hydrophobicity,such as KH550 mass fraction,KH550 treatment temperature,KH550 treatment time,ASOE grafting time and ASOE grafting temperature,were investigated.Grafted PSF membranes were characterized by Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy（ATR-FTIR）analysis,and the surface morphology after modification was visualized by Scanning Electron Microscope（SEM）.Results show that the hydrophobic groups are successfully grafted onto PSF membrane surface.The membrane hydrophobicity is improved with the water contact angle increasing from 87° to 116°.
