摘要: Monte-Carlo simulations of the configurations polymer chains in reinforced elastomers reveal extensive wrapping around particle clusters. The resulting increase chain entanglement density leads to a 3.5 power law dependence modulus on loading, perfect agreement with experimental observation. Our model also gives consistent molecular explanation Payne effect and associated energy dissipation strained elastomers.
