Particles are known to disperse best in solvents of similar hydrophobicity. This is commonly known as the similarity rule or “Likes dissolve Likes”. In this study, it was demonstrated that in addition to surfactants and surface derivatization other methods of dispersing particles in media of dissimilar polarity are possible. It was achieved using nanostructurade surface interface of dispersed particles. Realization of unconventional surfactant-less dispersion has broad fundamentals and technological impact due to wide-spread use of particle dispersions and environmental problems associated with surfactants.
