  • Process for Producing Polymer-Modified Nanoparticle
    Publication number: 20070249747
    Abstract: The present invention provides a process for producing polymer-modified nanoparticles in which all kinds of nanoparticles can be economically and easily isolated and purified, and obtained in the form of nanoparticles strongly bonded to a polymer. Hence, the nanoparticles can be easily formed into a coating or a film. The process includes mixing nanoparticles having a particle diameter of 100 nm or less which are selected from the group consisting of metals, metal oxides, and compound semiconductors, with a vinyl polymer having terminal SH group in a liquid to modify the surfaces of the nanoparticles with the vinyl polymer and then isolating the nanoparticles modified with the vinyl polymer from the solution.
