Abstract

Abstract : Fe3 O4 @HTC nanocapsules synthesized using a nanocasting method exhibited enhanced electromagnetic wave attenuation properties. Abstract : Magnetic nanocapsules with Fe3 O4 nanorods as the core and hydrothermal carbon (HTC) as the shell have been synthesized using a nanocasting method. Due to the strong shape anisotropy of the nanorods, the nanocapsules exhibit a higher coercivity and increased resonance at the high frequency range. Benefiting from the improvement of dielectric loss and magnetic loss at high frequency, the Fe3 O4 @HTC nanocapsule composites show superior microwave attenuation properties.
