流動光学的手法を用いた高分子化イオン液体のsub-Rouseモードの検討

抄録

Dynamic viscoelasticity and birefringence of two poly(1-butyl-3-vinylimidazolium) based polymerized ionic liquids, PC₄VICPFSI and PC₄VINfO, are investigated by using hand-made shear and tensile rheo-optical apparatus for a further consideration of sub-Rouse mode in polymerized ionic liquids systems. Sub-Rouse mode spectrum for PC₄VICPFSI whose counter anions is the same chemical structure as TFSI^- and different shape showed the same component function as sub-Rouse mode for PC₄VITFSI. On the other hand, sub-Rouse mode spectrum for PC₄VINfO whose counter anions is the same ionic size as TFSI^- but different chemical structure became sharper than that of PC₄VITFSI. This result indicated that plasticization effect of counter anions would be more responsible for sub-Rouse mode.
