초록

Polyhydroxyamide(PHA), a precursor polymer of polybenzoxazole(PBO), was synthesized by low temperature polymerization of 3,3'-dihydroxybenzidine(DHB) and isophthaloyl chloride(IPC) in N,N-dimethylacetamide (DMAc) medium. MWNT dispersions were prepared by ultrasonication of pristine MWNT(p-MWNT) and acid-modified MWNT(a-MWNT) in DMAc. PHA/a-MWNT and PHA/p-MWNT nanocomposite films were prepared by casting of mixed solution. The tensile properties of PHA/a-MWNT nanocomposite films were enhanced compared with those of pure PHA. DSC and TGA analyses revealed that the PHA/a-MWNT nanocomposites cyclized at lower temperature and showed better thermal stability compared to the pure PHA film.
