Claim:
1. A method for preparing polymer-nanoparticles having a core-shell structure, the method comprising preparing a suspension containing a polymer solution and nanoparticles; adding the suspension to an ionic liquid or an apolar solvent having a density of 1.05 to 1.80 g/cm removing the remaining polymer solution separated at an upper portion of the ionic liquid or the apolar solvent, wherein the polymer solution is one or two selected from polyamic acid, polyetherimide, polysulfone, or an ion conductive copolymer, wherein the ionic liquid is a compound containing a cation represented by the following Chemical Formula 2 or one or two or more anions selected from PF (R 1 to R 3 are each independently present and are hydrogen or (C1-C10) alkyl).
