Free-energy driven dispersion formation is of intense interest because microscopic to nanoscopic phase separation from macroscopic phases of chemical components involves an intriguing balance of chemical forces that results in apparent thermodynamic stability. We describe designs and syntheses of examples of such dispersions based on organic and inorganic-organic hybrid nanoparticles. A key attribute of such examples is their incorporation of polymerized ionic liquids (PIL) that also impart stimuli-responsive behaviors to such nanoparticles and dispersions derived from such nanoparticles. Such systems are illustrated to undergo reversible first and second order phase transitions and promise to provide bases for development of mesoscale thermodynamics of crystallization, precipitation, crystallization frustration, and multiphase coexistence. They also are shown to enable preparation of functional coatings and bulk materials of diverse types including mitigation of embrittlement in nanofiller composites, thermal conductivity in the mid-diamond range (kW/m/K), and solvent-free liquid biomacromolecules.<br/>
