Thermal Roughening and Deroughening at Polymer Interfaces in Electrophoretic Deposition

Abstract

Thermal scaling and relaxation of the interface width in an electrophoretic deposition of polymer chains is examined by a three-dimensional Monte Carlo simulation on a discrete lattice. Variation of the equilibrium interface width WrW_r with the temperature TT shows deroughening WrTδW_r \propto T^{-\delta}, with δ1/4\delta \sim 1/4, at low temperatures and roughening WrTνW_r \propto T^{\nu}, with ν0.4\nu \sim 0.4 at high temperatures. The roughening-deroughening transition temperature TtT_t increases with longer chain lengths and is reduced by using the slower segmental dynamics.
