    • Jiang, Y.; Lookman, T.; Sayers, A. B.; Douglas, J. F. Unpublished. The Cahn - Hilliard model of phase separation in combination with the Helfrich model of the surface elasticity shows that the scale of the film phase separation pattern can pin, at least transiently, at long times due to surface elasticity. See also references 43 and 58. There are also interesting simulations of elastic effects in alloy phase separation (Onuki, A.; Nishimori, H. Phys. Rev. B 1991, 43, 13649.), which show that elasticity can modify the coarsening dynamics from the conventional one-third power scaling of ordinary phase separation. Smaller apparent coasening exponents are reported in this work.

The exact calculations of the ordering temperature of systems with interacting boundaries in this work suggest that omer basic phenomena must be considered in thin block copolymer films than just a nonmonotonic dependence of the orderdisorder temperature with film thickness. Specifically, mese illustrative calculations show that the ordering process can involve two distinct ordering temperatures when the boundary interaction strongly induces ordering in the film, a physical situation that is thought to be prevalent in block copolymer films. These calculations also indicate that the shift of the order, disorder transition temperature can be strongly dependent on the magnitude of the substrate interaction, a phenomenon that could have tremendous consequence for the ordering of block copolymer films on chemically patterned substrates.
