Abstract
The orientation dynamics of a monolayer of a nematic polymer solution were examined for both extensional and simple shear flows. In extensio nal flow, a 'strong flow/weak flow' criteria was investigated and foun d to occur at a critical rate of strain that was predicted by the simp le molecular model of Doi and Hess. In simple shear flow, evidence of director wagging and flow alignment was obtained. (C) 1998 Elsevier Sc ience B.V. All rights reserved.
