“…Due to the high saturation magnetization, high initial permeability of nickel, the previous work mainly investigated the effects of various Ni-based composites with dielectric shells on the microwave absorption performances [10,[12][13][14]. Ni-based core-shell structure with the semiconductor TiO 2 shells have been rarely focused on [15,16].…”

Core-shell Ni/TiO 2 composite microspheres with different crystallinity have been prepared at various reaction times by the solvothermal method. The crystal structure and morphology of the products were investigated by X-ray diffraction, field-emission scanning electron microscopy and transmission electron microscopy. The microwave absorption properties of the core-shell Ni/TiO 2 composites were investigated at 1.0-18.0 GHz. The results show that the morphology and microwave absorption performances of Ni/TiO 2 composites were largely influenced by the crystallinity of TiO 2 shells. The crystallinity of anatase TiO 2 can be increased with increasing reaction time. Minimum peaks of Ni/TiO 2 composites shift to the high frequency with increasing the crystallinity of anatase TiO 2 , which are due to high thermal conductivity of high crystallinity of TiO 2 . The Ni/TiO 2 prepared at 36 h exhibits the best microwave absorption properties with minimum reflection loss of -16.9 dB at 14.1 GHz.

“…The electromagnetic (EM) wave pollution deriving from the rapid development of wireless communication devices, such as the local area network system and radar system, has become an unavoidable problem and even influenced health of human and the normal operation of electronic equipment [1][2][3]. Therefore, in order to protect the body from harm of these EM wave, the design and exploration of EM wave absorption fabric have attracted a great deal of interest which desired to effectively attenuate EM energy by dissipating them through interference and converting them into thermal energy [4][5][6].…”

Abstract. In this study, the CoFe 2 O 4 -PANI/PET fabric with microwave absorption and electrical properties was successfully prepared by a facile method. Firstly, the PANI in emeraldine base form was prepared by chemical oxidative polymerization. Secondly, the CoFe 2 O 4 nanoparticles and PANI solution were uniformly dispersed in epoxy resin and coated on the PET fabric. Finally, the conductive properties of the coating surface were obtained by doping. The resultant fabric was investigated by FTIR, SEM and TGA to check its chemical structure, surface morphology and thermal stability. The results of this fabric demonstrated efficient microwave absorption performance and broad absorption bandwidth, which indicating its potential application in microwave adsorption fields.

“…[1,2] Microwave absorbing material can absorb electromagnetic waves within a certain frequency range, so that the electromagnetic waves of incident on the material surface converted into other energies, thus reducing the reflection of electromagnetic waves greatly. The absorbing properties of the magnetic materials are considered to be strongly associated with their sizes, shapes and structures, etc.…”

RGO/Ni nanocomposites were prepared by in situ method. The microstructure and electromagnetic properties of the samples were investigated by X-ray diffraction, scanning electron microscopy and a vector network analyzer. Graphene oxide and Ni2+ at the same time reducing the synthesis RGO/Ni nanocomposite have wide reflection loss band can reach 1.6GHz. Nickel is deposited directly on graphene synthesis RGO/Ni nanocomposite have relatively sharp absorption peaks can reach -21.46 at 14.46GHz. The efficient complementarities between magnetic loss and dielectric loss can also contribute to the microwave absorption.
