Study on the preparation and characterization of ecofriendly polyimide films with differentamounts of 1,2-dimethylimidazole |
| 초록 |
Poly (amic acid) salt (PAAS), ecofriendly polyimide (PI) precursor, was synthesized from 3,3′,4,4′-biphenyltetracarboxylic dianhydride and p-phenylenediamine in an aqueous solution with 1,2-dimethylimidazole (DMIZ) acting as an organic base as well as an imidiation catalyst. The synthesized PAAS aqueous solution was converted to PI film by thermal imidization after producing gel film by the doctor blade coating method. To investigate the thermal imidization behavior of PAAS, the chemical and structural properties of the film were observed at the various temperatures corresponding to the steps of solvent evaporation, imidization, and annealing. Water-based PAAS was completely converted to the PI at the lower temperature due to the presence of DMIZ compared to that of PAA that is the conventional PI precursor synthesized in an organic solvent. We will present the chemical, thermal, and mechanical properties of ecofriendly PI films in viewpoints of DMIZ doses. |
