Highly ordered arrays of polyamide 6 (PA6) nanotubes were successfully prepared using photolithography via polymer solution wetting the anodic aluminum oxide (AAO) templates. The samples were examined by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD). The crystal structure and the crystallinity of the samples were influenced by the presence of nanopores in the AAO template. Nanopore-induced crystal transformation from the alpha-form to the gamma-form of PA6 was confirmed by XRD, and the formation of gamma-form crystal was enhanced by the presence of nanopores in the AAO template. The formation of gamma-form crystal was also discussed. These results indicated that nanopores provided favorable conditions for the crystallization of y phase.
