Using nanoparticles to control microstructure in polymer blends
Phase separated polymer blends have microstructures at length scales that are typically of the order of microns. The inclusion of nanoparticles can arrest the growth of phase separated domains resulting in much finer length scales. The diffusive equation of motions for the local concentration of the polymers and the nanoparticles will be coupled to the thermodynamics driving phase separation and to the hydrodynamic description of fluid flow. The resultant partial differential equations will be solved numerically, taking advantage of the parallel capabilities of graphics processing units.
