Coarse-grain molecular dynamics simulations of nanoparticle-polymer melt: dispersion vs. agglomeration.
In this work, we study the influence of polymer chain length (m), based on Lennard-Jones potential, and nanoparticle (NP)-polymer interaction strength (ɛnp) on aggregation and dispersion of soft… Expand
