Abstract: Atomistic simulations have been very useful for predicting the viscoelastic properties of polymers but face great difficulties in accessing the dynamics of dense, well entangled long-chain melts with relaxation times longer than μs due to… read more here.

Abstract: Although the tube models have attained remarkable success, development of a simulation method for entangled branch polymer dynamics is still a challenge. In this study, the multichain slip-spring model has been examined to branch polymers… read more here.

DOI: 10.1098/rsos.191046
Abstract: The constraint release (CR) mechanism has important effects on polymer relaxation and the chains will show different relaxation behaviour in conditions of monodisperse, bidisperse and other topological environments. By comparing relaxation data of linear polyisoprene… read more here.
