Computationally Efficient Field-Theoretic Simulations for Block Copolymer Melts
Beardsley, T.M.; Spencer, R.K.W.; Matsen, M.W. (American Chemical Society, 2019-11-12)Field-theoretic simulations (FTS) provide fluctuation corrections to self-consistent field theory (SCFT) by simulating its field-theoretic Hamiltonian rather than applying the saddle-point approximation. Although FTS work ... -
Effect of chain stiffness on the entropic segregation of chain ends to the surface of a polymer melt
Blaber, Steven; Mahmoudi, Pendar; Spencer, Russell; Matsen, Mark (2019)Entropic segregation of chain ends to the surface of a monodisperse polymer melt and its effect on surface tension is examined using self-consistent field theory (SCFT). In order to assess the dependence on chain stiffness, ... -
Fluctuation effects in blends of A+B homopolymers with AB diblock copolymer
Spencer, Russell; Matsen, Mark (AIP, 2018-05)Field-theoretic simulations (FTS) are performed on ternary blends of A- and B-type homopolymers of polymerization N_h and symmetric AB diblock copolymer of polymerization N_c. Unlike previous studies, our FTS are conducted ...
