Polyimide(PI) belongs to the super engineering plastic that is getting a spotlight ever since it is developed with excellent thermal stability, mechanical properties, chemical resistance, electrical properties due to its rigid chain structure. Polyhedral oligomeric silsesquioxane(POSS) is organic-inorganic hybrid material itself and it has excellent thermal stability, mechanical properties, and heat-resistant property. In this study, hybrid polyimide was prepared by physically mixing of poly(amic acid)(PAA) and POSS- NH3+, which was followed by heat imidization. PAA can be good compatible with POSS- NH3+ due to physical bonding between PAA and POSS-NH3+. |
