Abstract
A method for transferring inorganic oxide nanoparticles from aqueous phase to organic phase. A modifier is used to change the surface polarity of inorganic oxide nanoparticles, followed by using proper solvents to transfer the modified inorganic oxide nanoparticles form aqueous phase to organic phase. The organic dispersion of modified inorganic oxide nanoparticles can be combined with a polymer to provide a polymer composite with the nanoparticles uniformly dispersed therein.
