Intermolecular Interaction Induced Hierarchical Transformation in 1D Ionic Liquid and Aluminum Hydroxide Nanohybrids |
| 초록 |
We examined both room temperature ionic liquid (RTIL)-induced shape formation (RISF) mechanism and nano-confinement effect induced by intermolecular interactions between RTILs (acting as template and confined-fluid) and aluminum hydroxide crystallites (acting as building blocks and pore walls), employing a 2D IR correlation spectroscopy (COS). RTIL/aluminum hydroxide nanohybrids were hierarchically transformed in the molecular structures, morphologies, and phases of materials during an ionothermal process with respect to the concentration of RTIL. RTIL/aluminum hydroxide nanohybrids revealed unexpected physical behaviors, including glass transition variation of RTIL in confined environments and phase transition from nanosolids to nanoliquids affected by the changes of the melting points. 2D IR COS proved that sequentially spatial reorientation and kinetically conformational changes were related to intermolecular interaction induced-self assembly and confinement effect of RTILs. |
