Polymer reference interaction site model
WebThe three-dimensional reference interaction site model (3D-RISM) provides the solvent structure in the form of a 3D site distribution function, [Math Processing Error] g γ U V ( r), for each solvent site, [Math Processing Error] γ. It enables, at modest computational cost, the calculations of thermodynamics, electronic properties and ... Weberties of hard- and soft-core generic polymer models, which has rarely been reported [14], to further reveal their differences. For this purpose we choose the polymer reference in-teraction site model (PRISM) theory proposed by Schweizer and Curro [15], which has been applied to many polymeric systems, including homopolymer melts, solutions,
