Single crystals of polyethylenes with different molecular weight and of poly(d-lactide) were examined with atomic force microscopy. Morphologies of single crystals and their aggregates formed by overlaying as well as multilayer crystals are shown. Elevated diagonals caused by sectorization were found on crystals of both polymers. The nanoscale images demonstrate a grain structure of the lamellar surfaces with lateral features in the 5-15 nm range and roughness of about 1 nm. Polyethylene and the polylactide crystals exhibit some additional directional surface structure. The results are discussed in terms of surface organization.
