제목 EMI shielding properties of nanoparticle/CNF composites
초록 On the basis of EMI(electromagnetic interference) shielding mechanism, the effective materials for EMI should absorb electromagnetic waves as well as reflect them. Absorbing materials require electric or magnetic dipoles intrinsically. Otherwise reflecting materials have to possess their own electrical conductivity and need larger surface area based on skin effect. Furthermore, EMI shielding materials need to be light-weight and flexible nowadays. In this work we added BaTiO3, Fe3O4 nanoparticles having both electric and magnetic dipoles according to weight fraction into the carbon nanofiber as the light-weight and flexible EMI materials that are able to effectively block electromagnetic waves. We measured electrical conductivity by using 4-point probe. The structure was investigated by XRD. The morphology of the nanofiber web was confirmed by SEM and TEM. EMI shielding capability of the carbon nanofiber web was measured by network analyzer.
