【摘要】 由全反射红外光谱和场发射电子显微镜证实,利用氧化还原可成功地引发甲基丙烯酸在酚酞型聚醚砜膜表面的接枝聚合。继而,接枝膜在不同pH下的水通量测定实验表明,该接枝膜膜孔径的变化具有着显著、快速、可逆的pH响应性。更多还原

【Abstract】 Confirmed by Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy(ATR-FTIR)measurements and Field Emis- sion Scan Electrical Microscopy (FESEM) observations,methylacrylic acid can be grafted successfully onto the membrane surface using the in-situ redox-graft pore filling polymerization technique.Furthermore,through the hydraulic permeability experiments,the grafted membranes prepared using the reported method exhibited marked,rapid and reversible pH-response.更多还原
