PURPOSE: An environment-friendly coating method of a vehicle using iron oxide nano-particle photonic crystal is provided to gain good color sense, and to adjust colors according to the intensity of a magnetic field. CONSTITUTION: An environment-friendly coating method of a vehicle using iron oxide nano-particle photonic crystal includes the following steps of: manufacturing iron hydroxide powder by reacting iron precursor compounds and a base; washing hydroxy iron with water; separating the water and the hydroxy iron; manufacturing amorphous hydroxy iron nano particles of a colloidal phase by mixing the hydroxy iron and polymer plastic; manufacturing the hydroxy iron nano particles; manufacturing three-dimensional iron oxide nano particles photonic crystals; and coating the photonic crystals on an object(13). |
