Transparent dispersion of nanoparticles and applications to fabricate advanced organic-inorganic composites

How to disperse the inorganic nanoparticles mono-uniformly in the organic matrices is the key challenge of innovation of new generation of organic-inorganic nanocomposites. In this paper, a simple strategic method by incorporating the transparent dispersion of nanoparticles into organic matrix was proposed to prepare transparent organic-inorganic nanocomposites. The transparent dispersions of nanoparticles in liquid solvents were synthesized by our proposed novel high-gravity reaction coupled with extraction-phase transfer （HGRT） technology. By such strategy, the various transparent organic-inorganic nanocomposites with unique functions were fabricated, where the inorganic nanoparticles were all dispersed at the nano-scale. The preparation process principle, scale-up operations and the properties of functional transparent nanoparticle dispersions as well as their applications in the innovation of nanocomposite films for glass energy-saving, nano-lubrications for high railways, advanced transparent flexible optical nanomaterials with the high content of nanoparticles （60 wt%） were reviewed.
