Polyimides (PIs) are the most useful superengineering plastics for various applications such as aerospace, electronics, and other industries, because of their superior mechanical properties, high glass transition temperature, excellent thermal stability, and good chemical resistance. However, PIs are generally synthesized using organic solvents such as N-methyl pyrrolidone (NMP), dimethylformamide (DMF) and m-cresol, which are hazardous to environment. Therefore, synthesis of polyimides through the green chemistry would be attracted. We prepared polyimide powders from pyromellitic dianhydride (PMDA), and 4,4’-oxydianiline (ODA) using water-containing solvent mixture. The synthesized polyimide showed higher thermal decomposition temperature than conventionally synthesized polyimide using organic solvents. |
