Orientational Ordering of Polymers by Atomic Force Microscope Tip-Surface Interaction

ON MAN LEUNG 1 and M. CYNTHIA GOH 1

1 Department of Chemistry, University of Toronto, Toronto, Ontario, Canada M5S 1A1

Results of studies on the interaction between the tip of an atomic force microscope and polystyrene molecules in a film spread on a surface are reported. The tip produces a persistent deformation on the film; some of the polymer molecules are eventually pulled up by the tip. Nanometer-size structures are induced, resulting in a pattern that is periodic and is oriented perpendicular to the scan direction.
