Correlation of Nanowear Patterns to Viscoelastic Response in a Thin Polystyrene Melt

Abstract

The response of a thin-film polystyrene melt to a raster-scanned scanning force microscope tip was investigated. At high temperatures the scanning process induced intricate pattern formation whose quantitative characteristics were compared at different temperatures and scan rates. The dependence of the patterns on temperature and scan rate was consistent… (More)
