Abstract

In this study, we have successfully parameterized the coarse-grained (CG) model of cis-1,4-polyisoprene (main component of natural rubber) based on the MARTINI force field. An isoprene monomer is mapped into one bead of CG model. The structure, bulk and thermodynamics properties of cis-1,4-polyisoprene with new CG model are well comparable to the atomistic simulation model and experiment. Our CG model of cis-1,4-polyisoprene will be helpful to study in the advanced rubber nanocomposite materials. ฉ Published under licence by IOP Publishing Ltd.
