Dynamics of Terminally Anchored Polymeric Chains

The conformation of terminally anchored chains is of importance in applications such as chromatography with reversed phases, ceramic-supported polymer membranes, biocompatible surface, rheology, composites, and lubrication. Of particular interest in this project is the conformation of such chains subjected to shear and elongational flows. Experimental studies have been conducted with terminally anchored chains in which the hydrodynamic response of the chains was studied. Also, Brownian-dynamics models that account for the detailed motion of model terminally anchored chains have been developed. Current work is focusing on developing a modeling framework to account for the interaction of surface chains.
