Preparation and characterization of conductive filler used for electromagnetic shielding materials
In present work, two conductive filler (carbon fiber with Nickel (Ni) coatings and carbon fiber with Nickel/Fe3O4 nanoparticle (Ni/Fe3O4-NPs) composite coatings) were prepared by electrodeposition. Microstructure observation indicated that the coatings were deposited uniformly on the surface of fiber. Vibrating sample magnetometer (VSM) and electromagnetic interference (EMI) shielding test showed that the two conductive filler has good saturation magnetization and EMI shielding effectiveness.The conductive filler of carbon fiber with Ni/Fe3O4-NPs composite coatings was more excellent. They are promising for application in electromagnetic shielding materials.
