摘要:Abstract(#br)To verify the structure-properties relation of elongated clay nanocomposite (NC) gels through two-dimensional scattering patterns (2DSPs), we performed coarse-grained molecular dynamics (CGMD) simulations of a bead-spring model of NC gels. In order to reproduce ...

摘要:Abstract(#br)Coarse-grained molecular dynamics (CGMD) simulations of a polymer network filled with explicitly polydisperse nanoparticles (NPs) were performed to evaluate the changes in two-dimensional small-angle scattering (2D-SAS) patterns under elongation. The effect of a...

摘要:Abstract(#br)The single-chain folding of an isotactic polypropylene (iPP) chain through united atom (UA) molecular dynamics simulations under quenching was investigated using force fields (FFs) based on TraPPE-UA. We estimated the degree of local rigidity of the folded chain alon...
