Bidirectional mapping between self-consistent field theory and molecular dynamics
Thompson, Russell B.; Sewell, Thomas; Rasmussen, Kim; Bedrov, Dmitry; Smith, Grant (AIP Publishing, 2007-10-08)A bidirectional mapping scheme that bridges particle-based and field-based descriptions for polymers is presented. Initial application is made to immiscible homopolymer blends. The forward mapping (upscaling) approach ... -
Elastic moduli of multiblock copolymers in the lamellar phase
Thompson, R. B.; Rasmussen, Kim; Lookman, T. (AIP Publishing, 2004-02-22)We study the linear elastic response of multiblock copolymer melts in the lamellar phase, where the molecules are composed of tethered symmetric AB diblock copolymers. We use a self-consistent field theory method, and ... -
Nanoparticle-regulated phase behavior of ordered block copolymers
Thompson, R.B.; Gaines, Michelle K.; Smith, Steven D.; Samseth, Jon; Bockstaller, Michael R.; Rasmussen, Kim; Spontak, Richard J. (RSC publishing, 2008-06-30)Although block copolymer motifs have received considerable attention as supramolecular templates for inorganic nanoparticles, experimental observations of a nanostructured diblock copolymer containing inorganic ... -
Ordering and Reverse Ordering Mechanisms of Triblock Copolymers in the Presence of Solvent
Thompson, Russell B.; Rasmussen, Kim; Maniadis, Panagiotis; Kober, Edward M. (MDPI, 2009-02-27)Self-consistent field theory is used to study the self-assembly of a triblock copolymer melt. Two different external factors (temperature and solvent) are shown to affect the self-assembly. Either one or two-step self-assembly ...
