| 제목 | A Study on the Structure of Alkylamine inside the Confined Space of α-Layered Zirconium Phosphate |
| 초록 | Highly-functionalized inorganic layered material, α-zirconium phosphate (α-Zrp) was prepared to study interlayer structure of alkylamine in confined space of layered inorganics. Since the charge density, cationic exchange capacity (CEC), on the layer surface of synthetic α-Zrp was high enough to take all-trans conformers of intercalated alkylamine, its characteristic structures in α-Zrp interlayer (i.e., interdigitated layer or bilayer) were clearly obtained by monitoring d-spacing of host material, α-Zrp, based on the XRD. As intercalated amount of mono-alkylamine whose one endfunctional amine was tethered onto α-Zrp surface increases, its interlayer structure was changed from interdigitated layer to bilayer. The difference in thermal stability and crystalline melting temperature of both interdigitated layer and bilayer for intercalated alkylamine is investigated with TGA and DSC. The effect of solid-to-liquid phase transition of intercalated akylamine on the structure of host material, α-Zrp, is also studied using in-situ XRD. |
