By employing molecular dynamics simulations, we explored the conformation transition of nanoparticles (NPs) in semiflexible ring polymer nanocomposite melts. A novel aggregation–dispersion transition for NPs in ring polymer nanocomposites occurs when the bending energy of ring chains increases. The conformations of flexible ring chains near NPs are radial distribution, and the entropic ...
Grinding and Dispersion Equipment For Nano Scale Applications Harry Way, Technical Director, NETZSCH Fine Particle Technology, LLC INTRODUCTION Ever since Tokyo University of Science professor Norio Taniguchi coined the term, "nanotechnology" in 1974, we have heard much about nanoparticles and what can be done with them.
