Orientational ordering of grafted nonmobile rod polymers

Abstract

SYNOPSISWe studied the orientational ordering of grafted rod polymers on the surface. The rod polymers were nonmobile and allowed to have two configurations: either lying down on the surface or standing up. The only interaction between the rods were hard core interaction. We computed the orientational order parameter using the recently developed random local field theory. We found that the order parameter increased monotonically as a function of the concentration of the rods and, thus, there existed no pancake-brush transition. 0 1995
