Thermally Reaaranged (TR) Polymer Membranes Prepared via Solution Polymerized Hydroxy Polyimides for Gas Separation |
| 초록 |
Fluorinated hydroxy polyimides(HPI)were prepared by two-step method with either thermal or chemical imidization of poly(amic acid)s. In this study, the acquired HPIs were compared in terms of their solubility, thermal properties and high performance for gas permeability and permselectivity. HPIs prepared by chemical imidization were soluble in common organic solvents but those prepared by thermal imidization were generally insoluble. HPI films were thermally treated up to 450oC for an hour to make PBO which showed excellent thermal stability thanHPIs and excellent performance for gas permeability. |
