Journal ArticleDOI
Nanoparticle Dispersion and Aggregation in Polymer Nanocomposites: Insights from Molecular Dynamics Simulation
TL;DR: It is found that the coarsening or aggregation process of the NPs is sensitive to the temperature, and the aggregation extent reaches the minimum in the case of moderate polymer-filler interaction, because in this case a good dispersion is obtained.
Journal ArticleDOI
Polymer???nanoparticle interfacial behavior revisited: A molecular dynamics study
TL;DR: A coarse-grained model-based molecular dynamics simulation is used to study the polymer-filler interfacial structural, dynamic and stress-strain properties, and indicates that although the mobility of interfacial polymer chains is restricted, there exist no "polymer glassy layers" surrounding the filler.
Journal ArticleDOI
The Interesting Influence of Nanosprings on the Viscoelasticity of Elastomeric Polymer Materials: Simulation and Experiment
TL;DR: In this article, the incorporation of nanosprings can improve the mechanical strength of the elastomer matrix through nanoreinforcement and considerably decrease the hysteresis loss.
Journal ArticleDOI
Nanoparticle chemically end-linking elastomer network with super-low hysteresis loss for fuel-saving automobile
Jun Liu,Zijian Zheng,Fanzhu Li,Weiwei Lei,Yangyang Gao,Youping Wu,Liqun Zhang,Zhong Lin Wang,Zhong Lin Wang +8 more
TL;DR: In this paper, a chemically end-linking elastomer network with nanoparticles acting as netpoints to chemically connect the dual end-groups of each polymer chain to form a network, exhibits excellent static and dynamic mechanical properties of super-low DHL.
Journal ArticleDOI
Molecular dynamics simulations of the structural, mechanical and visco-elastic properties of polymer nanocomposites filled with grafted nanoparticles
TL;DR: It is shown that the non-linear relation of G' and G'' as a function of shear strain amplitude decreases with the increase of Σ and Lg, which is consistent with experimental observations and may provide some rational means to tune the mechanical and visco-elastic properties of end-grafted NPs filled polymer nanocomposites.
