Abstract
Lateral force microscopy (LFM) measurements are performed on solution- grown lamellar crystals of isotactic poly(4-methyl-1-pentene). Fold-do main boundaries are observed to protrude above the surface of the crys tals. Within the fold domains the magnitude of the friction signal at a given load was found to depend on the scan direction. Frictional ani sotropy is exhibited and is shown to be independent of topography. The observed friction anisotropy is discussed in terms of the structure o f the fold surface and ascribed to the presence of an ordered arrangem ent of folds. (C) 1998 Elsevier Science Ltd.
