Single crystals of the polyimide PMDA-ODA were grown from a 1.4% by weight solution of the precursor poly(amic acid) in NMP solvent. The morphology of the crystals was examined by high resolution electron (HREM) and atomic force microscopies (AFM). The crystals formed spherulitic bundles of well-defined lamellae similar to that typically observed in semicrystalline polymers. The crystallographic growth direction was found to be [010] in all cases. The nucleation and growth patterns of these… CONTINUE READING
