摘要: 选用二甲基乙酰胺(DMF)溶剂，将聚醚砜(PES)溶解，再与研磨处理的氯化钠(NaCl)致孔剂颗粒混合均匀，采用浇铸法制成PES/氯化钠(NaCl)材料。用去离子水抽提氯化钠形成PES多孔材料，研究PES的孔结构、孔隙率和吸水率等与成孔剂的关系。使用同一粒径致孔剂，得到的PES孔材料的吸水率随着致孔剂用量增大而增大，但是当PES与致孔剂超过一定质量比后，吸水率减小。使用三个不同粒径的致孔剂，PES孔材料的吸水率与孔结构尺寸没有线性关系。采用光学显微镜和扫描电镜对PES孔结构进行了表征，发现该材料是具有孔隙间连通的三维多孔材料。
Abstract: Dimethylacetamide (DMF) was used as the solvent to dissolve the polymer, and then mixed with the treated sodium chloride (NaCl) porogen granules. The polymer/sodium chloride (NaCl) materials were prepared by casting method. The PES porous materials were extracted with deionized water to study the pore structure, porosity and water absorption of PES. Using the same particle size porogen, the water absorption of the PES pore material increases with the amount of porogen, but when the mass ratio of PES and porogen is more than a certain degree, the water absorption decreased. The water absorption of the PES pore material was not linearly related to the size of the pore structure using three porosens of different particle sizes. The PES pore structure was characterized by optical microscopy and scanning electron microscopy. It was found that the material was a three-dimensional porous material with inter-pore connectivity.
