Thermal Roughening and Deroughening at Polymer Interfaces in Electrophoretic Deposition
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
with the temperature shows deroughening ,
with , at low temperatures and roughening , with at high temperatures. The roughening-deroughening
transition temperature increases with longer chain lengths and is reduced
by using the slower segmental dynamics.Comment: This is a work of the U.S. Government and is not subject to copyright
