Polymeric membranes, based on a polysulfone-type aromatic polyether matrix, were successfully developed via the non-solvent induced phase separation (NIPS) method. The polyethersulfone type polymer poly[2-(4-(diphenylsulfonyl)-phenoxy)-6-(4-phenoxy) pyridine] (PDSPP) was used as the membrane matrix, and mixed with its sulfonated derivative (SPDSPP) and a polymeric porogen. The SPDPPP was added to impart hydrophilicity, while at the same time maintaining the interactions with the non-sulfonated aromatic polyether forming the membrane matrix. Different techniques were used for the membranes' properties characterization. The results revealed that the use of the non-sulfonated and sulfonated polymers of the same polymeric backbone, at certain compositions, can lead to membranes with controllable porosity and hydrophilicity.
基于聚砜型芳香族聚醚基体的聚合物膜通过非溶剂诱导相分离（NIPS）法成功制备。聚醚砜型聚合物聚[2-(4-(二苯基磺酰基)-苯氧基)-6-(4-苯氧基)吡啶]（PDSPP）用作膜基体，并与它的磺化衍生物（SPDSPP）和一种聚合物致孔剂混合。添加SPDPPP以赋予亲水性，同时保持与形成膜基体的非磺化芳香族聚醚之间的相互作用。采用不同技术对膜的性能进行表征。结果表明，在特定组成下使用具有相同聚合物主链的非磺化和磺化聚合物，可制得具有可控孔隙率和亲水性的膜。
