制备了聚乳酸(PLA)和聚偏氟乙烯(PVDF)共混物，并用介电弛豫谱(DRS)研究了PMI离子液体链段对聚乳酸和聚偏氟乙烯(PVDF)相容性的影响。与PEGMA与乙烯基咪唑(PMV)共聚物相比，PMI能明显改善聚乳酸与PVDF的相容性。差示扫描量热仪(DRS)表明，共混物的松弛行为与聚乳酸和聚偏氟乙烯的相容性有关，这与Maxwell-Wagner-Sillars(MWS)界面极化相一致。在相同温度下，聚乳酸/聚偏氟乙烯/聚偏氟乙烯共混物的ε‘远高于聚乳酸/聚偏氟乙烯/聚偏氟乙烯共混物，这是由于聚偏氟乙烯的离子迁移率刺激了MWS界面极化的结果。
Biodegradable polylactide (PLA) and polyvinylidene fluoride (PVDF) blends containing the copolymer of PEGMA and 1‐vinyl‐3‐ethylimidazolium bromide (PMI) were prepared, and the effects of ionic liquid segments of PMI on the compatibility of PLA and PVDF were investigated by dielectric relaxation spectroscopy (DRS). PMI can obviously improve the compatibility of PLA and PVDF, compared with the copolymer of PEGMA and vinyl imidazole (PMV). DRS showed that the compatibility of PLA and PVDF was related to the relaxation behavior of the blends, which was identified with Maxwell‐Wagner‐Sillars (MWS) interfacial polarization. Theε' of PLA/PVDF/PMI blends was much higher than that of PLA/PVDF/PMV blends in the same temperature, resulting from the stimulation of MWS interfacial polarization by the ion mobility of PMI.
