Abstract
Disclosed is an inorganic-organic hybrid polymer composed of nano-particles on the surface using a dendrimer and a manufacturing method thereof, in which nanometer-sized inorganic (metal) particles are uniformly dispersed across the surface of the polymer and available as optically, electrically and magnetically functional materials. The method includes the steps of: forming a functional anhydride group on a polymer-based matrix; selectively adding metal or inorganic salts to the dendrimer to prepare either of dendrimer-metal precursor solution or dendrimer-inorganic particle solution; inducing the reaction between the functional anhydride group of the surface of polymer matrix with the solution to form a chemical bond between the matrix and the dendrimer; and reducing the metal ions or inorganic particle by irradiation of light.
