  • Publication number: 20140054511
    Abstract: The present invention provides a method for transferring phases of nanoparticles, which use a polymer with a molecular weight greater than 5,000 as a dispersant. The first step of the method of the present invention is to synthesize nanoparticles in the polymer aqueous solution. Next, an amphiphilic phase-transfer agent is added into the solution to coat the surface of nanoparticles with bipolar molecules, and then the mixture is added into an organic solvent to form a homogeneous solution. Finally, a salt and an alcohol are added into the homogeneous solution, and then an organic phase layer and an aqueous phase layer through a centrifugal method. The method of the present invention combines the advantages of aqueous process for preparing nanoparticles and transfers the same with a simple phase transferring process to obtain oil-phase nanoparticles, which can be applied to various fields.
