Coarse Grained Molecular Dynamics

In this work we have adopted coarse-grained molecular dynamics simulations to systematically investigate the effects of the grafting density and the grafted chain length on the structural, mechanical and visco-elastic properties of polymer nanocomposites (PNCs).

Coarse Grained Molecular Dynamics

Detailed coarse-grained molecular dynamics simulations are performed to investigate the structural and mechanical properties of nanoparticles (NPs) grafted with an amphiphilic AB diblock copolymer, with the A-block being compatible with NPs and the B-block being miscible with a homopolymer matrix.
