Molecular dissipation phenomena of nanoscopic friction in the heterogeneous relaxation regime of a glass former.

Abstract

Nanoscale sliding friction involving a polystyrene melt near its glass transition temperature Tg (373 K) exhibited dissipation phenomena that provide insight into the underlying molecular relaxation processes. A dissipative length scale that shows significant parallelism with the size of cooperatively rearranging regions (CRRs) could be experimentally… (More)
