Abstract：The conformations of ring polymer chain and the aggregation behavior of nanoparticle in nanocomposites are investigated by coarse-grained molecular dynamics.Nanoparticles exhibit three dispersion-aggregation states:contact aggregation,dispersion and tele bridging aggregation,which are consistent with the theoretical results.By altering the stiffness of ring chain,three typical conformations are obtained:middle adsorption,saddle-shaped adsorption and obit-shaped adsorption.The increasing of ring chain stiffness is benefit for the dispersion of nanoparticle in nanocomposites.
