A new type of polybenzimidazole films were prepared by synthesized PBI with ethylene oxide units. In this work, to synthesize PBI, novel tetraamine was synthesized terephthalic acid. Polyphosphoric acid was used as solvent. This synthesized PBI’s main chain EO units were changing the type of glycol. These films were successfully characterized for confirming the synthesis by the FT-IR and 1H-NMR. And various analysis method are used. Through these evaluations, we found that the PBI with main-chain ethylene oxide units could be the one of good candidates as the substrates for the flexible displays such as Flexible OLED or e-Paper. |
