离子液体液晶中高效离子传导通道的构筑与调控

Ionic liquid-based liquid crystals have received increasing attention during recent research, but their practical application is still limited. In this project, we focus on the ionic liquid-based liquid crystals to make a deep combination of excellent physicochemical properties of ionic liquids and the highly ordered well-defined nanostructures in liquid crystals. The purpose of this project is to explore the potential application of ionic liquid-based liquid crystals in ion-conductive materials and the influence of well-defined nanostructure on ion-conductive process. Moreover, stimuli-responsive ion-conductive channels, which have responsibility to UV-light, electric filed, magnetic filed, temperature or pH value, will be constructed with the introduction of liquid crystalline nanostructures. Meanwhile, one or two-dimensional ion-conductive channels can be obtained by the aligned liquid crystals which are perpendicular or parallel to the electrode surface. In order to improve the mechanical properties, nanostructured ion-conductive films can also be fabricated by in situ polymerization of liquid crystals as well as maintain the well-defined nanochannels. We expect this project can provide a new perspective on the preparation of novel low-dimensionally functional ion-conductive materials.
