Abstract
The present invention relates to a method for preparing polymer-nanoparticles having a core-shell structure by uniformly coating a polymer on metal and inorganic particles, polymer-nanoparticles prepared thereby, and a polymer-nanoparticle composite comprising the same, and more specifically, a method for preparing polymer-nanoparticles having a core-shell structure by uniformly coating a polymer on metal and inorganic particles, polymer-nanoparticles prepared thereby, and a polymer-nanoparticle composite including the same, wherein when forming a polymer coating layer on surfaces of particles that are not subjected to separate surface treatment, excessive polymers uncoated on nanoparticles are easily removed by adding to an ionic liquid or an apolar solvent so that the polymer coating layer is formed with a nanometer-scale uniform thickness and a dense coating density, thereby showing excellent dispersibility in a polymer matrix.
