Abstract: Disclosed is a nanoparticle generating unit, a nanoparticle coating unit, and a core-shell nanoparticle collecting unit are connected to link and continuously process generation of nanoparticles and a coating and collecting process. The nanoparticle coating unit is formed of a porous material or in a grid structure and a moving speed of the nanoparticles can be decreased using a speed adjustment member installed at a process passage of a coating chamber.

Abstract: Disclosed is a coating chamber having a process passage in which a coating process is performed, a particle supply means configured to supply nanoparticles into the process passage, a gas supply means configured to supply a carrier gas and a reactive gas serving as a source of a shell material into the process passage, and a low pressure forming means configured to form a low pressure in the process passage. The coating chamber has a speed adjustment member formed of a porous material or a grid and installed in the process passage, and as a moving speed of the nanoparticles is decreased due to flow resistance or collision of the nanoparticles passing through the speed adjustment member, first and second precursors supplied as the reactive gas move more rapidly than the nanoparticles to coat a thin film on the nanoparticles with the material.
