While much interest has been focused on the practical uses of polymer-nanoparticle hybrids, very little is understood about the science that underpins this important class of materials. For example, the factors governing the equilibrium miscibility of polymers and particles are not understood. In the same vein, the dynamics of these materials (viscosity and diffusion coefficients), which control their processing, are not explored, even though a range of very unexpected experimental results have been found. This talk will be a series of vignettes, a few experimental but mostly theoretical, that will consider several of these interrelated issues.
