As technology continues to advance, the trend toward designing smaller devices with higher performance capabilities is requiring many to innovate and visualize of new ways of managing heat and solving EMC/EMI issues in more efficient ways. Optimal thermal management and EMC/EMI shielding is decisive to enhancing a product’s overall lifespan or optimizing the performance in devices. For this purpose, we have investigated thermophysical and electromagnetic properties of heat-spreadable EMI composites including Fe-Cr ferromagnetic core and thermal conductive alumina shell layer. In this study, we fabricated ferromagnetic core-thermal conducting alumina shell particles via solvothermal process assisted by supercritical carbon dioxide with sol-gel processing. As a result, the thermal conductivities of the three-component composite sheets with nanostructured shell layer were well-predicted from the modified Pal model by considering the phonon scattering. |
