Properties of Water-based Polyimide Foams According to Various Monomer Components |
| 초록 |
Poly(amic acid) salt (PAAS) paired with tertiary amines is water-soluble polyimide precursor, which is easily converted to polyimide (PI) at relatively low temperature. The structural characteristics of PAAS is basically identical to the amphiphilic molecule that have hydrophilic head conjugated with hydrophobic bodies. Therefore, the PAASs are potentially suitable to stabilize interface between water and oil even it possible to produce high internal phase emulsion (HIPE) having over 74 vol% of internal phases. In here, we propose the preparation of macroporous PIs by using HIPE stabilized by PAAS as template with removing the solvents through freeze-drying. To identify the correlation between the chemical structure and mechanical properties, PAAS having various type of chemical structure have been utilized. The resulting PI foam materials are characterized by universal testing machine, scanning electron microscopy and thermogravimetric analysis. |
