Thermal Roughening and Deroughening at Polymer Interfaces In Electrophoretic Deposition
Physics and Astronomy
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 W-r with the temperature T shows deroughening W-r similar to T-delta, with delta similar to (1)/(4), at low temperatures and roughening W-r proportional to T-v, with v similar to 0.4, at high temperatures. The roughening-deroughening transition temperature T-t increases with longer chain lengths and is reduced by using the slower segmental dynamics.
