摘要：

The structure and contact faces of epitaxially crystallized isotactic polypropylene (iPP) in its alpha and gamma phases are investigated by electron microscopy, electron diffraction, and atomic force microscopy (AFM). AFM results with methyl group resolution help recognize which one of two possible contact faces interacts with the substrate. Structural analysis makes it possible at least in the alpha phase) to determine the hand of helices in contact with the substrate.
