Although nanoparticle loading is known to be an important factor influencing nancomposite properties, experimental and theoretical studies have found that the spatial organization of the nanoparticles also strongly influences macroscopic behavior. For instance, Jana and coworkers reported polybenzimidazole nanocomposite systems with morphologydependent proton conduction and storage modulus properties at a fixed nanoparticle loading. In their studies, the characteristic structure of the dispersed nanoparticles was altered by modifying the nanoparticle surface with various functional groups. Similarly, Akcora et al. reported tunability in mechanical properties of polymer nanocomposites at a fixed nanoparticle volume fraction by varying the grafting density and molecular weight of tethered chains, and attributed such behavior to the resulting modulation of the nanoparticles' self-assembled structure. A recent mesoscale simulation study of ours highlighted the potential for modifying nanoparticles structure to significantly influence the tracer diffusivity through nanocomposite gels in the presence of interface-assisted transport pathways.
