| 제목 | Synthesis of Metal-carbon Composite Composed of Expanded Graphite and Nanometal and its Properties |
| 초록 | Various methods of spreading heat are widely used in today’s electronics, which is one of major application of expanded graphite(EG)/Ag nanoparticle composite. Heat spreaders are used in die level packaging to spread heat from the microprocessor chip into the packaging. The potential of EG/Ag nanoparticle composites for the heat spreader should be verified. The synthesis of EG/Ag nanoparticle composites has been performed by the chemical reduction of Ag ions followed by the addition of expanded graphite into the Ag reducing solution. The prepared EG/Ag nanoparticle composites showed the uniform dispersion of Ag nanoparticle on the surface of expanded graphite. The EG/Ag nanoparticle composites exhibit relatively high thermal conductivities rather than that of pure expanded graphite. We suggest that the possibility of EG/Ag nanoparticle composites can be as a strong candidate for the advanced heat spreading material in the field of electronics. |
