EMI(electromagnetic interference) Shielding effect of electrospun carbon nanofiber web containing Fe3O4 or BaTiO3 |
| 초록 |
Based on EMI shielding mechanism, more effective EMI shielding materials should absorb electromagnetic wave as well as reflect it. Reflecting materials have to possess their own electrical conductivity. Otherwise, absorbing materials have to have electric or magnetic dipoles intrinsically. Generally, the electric and the magnetic dipoles are related to a dielectric constant and a magnetic permeability, respectively. In this research, in order to get more effective EMI shielding materials, carbon nanofiber web that has high electrical conductivity and high aspect ratio was spun by simple electrospinning process with high magnetic Fe3O4 with or high dielectric BaTiO3 additives. We measured electrical conductivity by using 4-point probe. Morphology of the nanofiber web was confirmed by SEM and TEM. The Structure was investigated by using XRD and XPS. EMI shielding capability of the carbon nanofiber web was measured by network analyzer. |
