将磺化金属-有机框架材料MIL-101(Cr)-SO3H成功引入到磺化酚酞侧基聚芳醚砜(SPES-C)中制备了不同填充量的SPES-C/MIL-101(Cr)-SO3H杂化膜并用于渗透汽化乙酸脱水。结果表明:所得杂化膜无明显缺陷。MIL-101(Cr)-SO3H的引入提高了杂化膜的亲水性并增大了杂化膜的自由体积参数。随着MIL-101(Cr)-SO3H填充量的增加,杂化膜的渗透通量不断增大,而分离因子呈先上升后下降的趋势。当MIL-101(Cr)-SO3H填充质量分数小于30%时,渗透通量和分离因子出现反“trade-off”效应。
The sulfonated metal-organic framework material MIL-101(Cr)-SO3H was successfully introduced into sulfonated polyarylethersulfone with cardo (SPES-C) to prepare SPES-C/MIL-101(Cr)-SO3H hybrid membranes with different loadings and used for pervaporation dehydration of acetic acid.The hybrid membranes had no obvious defects.The introduction of MIL-101(Cr)-SO3H improved the hydrophilicity and the free volume parameter of the hybrid membranes.With the increase of MIL-101(Cr)-SO3H loading,the permeation fluxes of hybrid membranes increased,while the separation factors increased first and then decreased.When MIL-101(Cr)-SO3H loading was less than 30%,the “anti-trade-off” effect appeared between the permeation flux and separation factor.
