Electrical Memory Behaviors of a Well-Defined Brush Polymer Bearing Oxadiazole-Based Mesogens depending on Change of Morphology |
| 초록 |
A new oxadiazole-containing brush polymer, poly-(5-phenyl-1,3,4-oxadiazol-2-yl-[1,10-biphenyl]carboxyloxyn-nonyl acrylate) (PPOXBPA), was synthesized. Its optical and electrochemical properties were investigated. This brush polymer was found to always self-assemble into a multibilayer structure Interestingly, when the polymer film was applied in devices with a bottom and top electrode, it showed either volatile or nonvolatile memory behavior, depending on the ordering and orientation of the multibilayer structure (particularly, the π_π stacked oxadiazole mesogen units), which could be controlled via thermal annealing. The switching mechanisms of these electrical memory behaviors were investigated. Collectively, these results demonstrate that this chemically well-defined brush polymer is suitable for use as an active material for the low-cost, mass production of high-performance, programmable volatile and nonvolatile memory devices via control of the morphological structure. |
