Kh. Kim et Wh. Jo, Effect of chain architecture of graft copolymer on the structure of adsorbed layer: a Monte Carlo simulation approach, POLYMER, 42(7), 2001, pp. 3205-3211
The effect of chain architecture of graft copolymer on the structure of an
adsorbed layer on a surface is investigated using an off-lattice Monte Carl
o simulation method. The graft copolymers used for the simulation have the
same composition but different chain architecture. The simulation results s
how that the layer thickness of multi-chains adsorbed onto the surface firs
t decreases with increasing the number of side chains, indicating that the
chain conformation of the adsorbed polymer becomes more flattened as the le
ngth of the side chain becomes shorter. When the length of the side chain d
ecreases further than a critical length, however, a slight increase in laye
r thickness is observed, accompanied with an increase in the population of
loosely bound chains. (C) 2001 Elsevier Science Ltd. All rights reserved.
