| 摘 要： | 采用FTIR表征了聚醚砜/微纳纤维素复合膜材料的官能团特征，利用XRD分析了复合膜材料的结晶度变化情况。研究了微纳纤维素质量分数的变化对膜亲水性能的影响。通过SEM观察了复合膜支撑层的膜结构。结果表明, 复合膜材料同时具有聚醚砜、微纳纤维素红外特征峰，且没有新峰出现，说明复合膜中微纳纤维素与聚醚砜为氢键缔合作用，无新官能团的产生，达到分子水平的相容。微纳纤维素的存在使得复合膜结晶性能增强，结晶度从37.7%增大至47.9%。随着微纳纤维素质量分数的增加，复合膜对水的范德华力和氢键力增强，亲水角从55.8°下降至45.8°，表面能从113.7 mN·m-2增加到123.5 mN·m-2，从而提高了复合膜材料的亲水性。复合膜多孔支撑层表面孔数较多，孔径有所增大，膜孔分布较为均匀。
