Multiscale Simulation of Polymer Nanocomposites in Processing: Challenges and Outlooks

Abstract:

This paper attempts to address current possibilities in the multiscale simulation of polymer nanocomposites (PNCs) in processing. To provide a comprehensive perspective, a number of PNCs were produced by the incorporation of nanoclays in different polymer matrices. The microstructure evolutions of the simulated counterparts of such systems were studied with and without shear flows in a dissipative particle dynamics (DPD) framework spanning from several nanometers up to a few microns. Transmission electron microscopy (TEM) was utilized to contrast the simulations against the actual nanocomposites. A satisfactory precision was achieved in the build-up of the simulated structures. A significant characteristic of anisometric particles was studied, namely the orientation of the particles due to the imposed flows. It was shown that the orientation of such particles could be well described. Finally, opportunities were addressed for the simulations to carry on to the higher scales.
