“…This includes graphene oxide/nickel nanofibers with hierarchical core/shell structure and vertically aligned graphene edge planes [78] or ZnFe 2 O 4 particles synthesised inside porous hollow carbon microspheres [77], where the multiple interfaces in the structure improved interfacial polarisation and thus the overall absorbing capabilities. A detailed review of the absorbing properties of various composites can be followed from the work of Kumar et al [87], Meng et al [88], Houbi et al [89] and Qin et al [90]. It must be emphasised that the majority of absorbing materials operate based on the matching thickness (quarter wavelength) principle.…”

Using carbon-fibre-reinforced polymer (CFRP) composites for electromagnetic interference (EMI) shielding has become a rapidly emerging field. This state-of-the-art review summarises all the recent research advancements in the field of electromagnetic shielding properties of CFRP composites, with exclusive attention paid to experimental work. It focuses on (1) important mechanisms and physical phenomena in the shielding process for anisotropic carbon-fibre composites and (2) shielding performance of CFRP materials as reported in the literature, with important performance-affecting parameters. The key properties which directly influence the shielding performance are identified, the most critical being the carbon-fibre concentration along with length for discontinuous carbon-fibre-filled polymers and the lay-up for continuous carbon-fibre-reinforced composites. The effect of adding conductive inclusions such as metal or carbon nanotubes is also reviewed. It is emphasised that processing conditions are strongly linked with the shielding properties of a composite. This is a first review, which covers all the recent advancements in the field of shielding properties of carbon-fibre-reinforced composites, with detailed analysis of factors influencing these properties and clear distinction between continuous and discontinuous reinforcement. It is shown that CFRP composites make a good candidate as an EMI shielding enclosure material.

“…Among these materials, transition magnetic metals (Fe, Co, Ni) with high specific magnetism, outstanding electric conductivity and low cost has attracted a lot of attention as MAM because of its excellent magnetic loss capability endowed by natural resonance and eddy current effects [ 5 , 6 , 7 , 8 ]. However, in order to achieve good impedance matching, so that the electromagnetic wave can incident into the material as much as possible rather than be reflected, it is required that the impedance of the material surface should be as close as possible to the characteristic impedance of free space, that is, the values of relative complex permeability and relative complex dielectric constant should be as close as possible [ 9 , 10 , 11 , 12 ]. Hence, the poor impedance matching which causes an undesirable microwave absorption capacity is still a great challenge to transition metals.…”

In Situ Reduced Multi-Core Yolk–Shell Co@C Nanospheres for Broadband Microwave Absorption

The preparation of yolk–shell microwave absorption materials with low density and excellent microwave absorption property requires reasonable design and economical manufacture. In this study, an efficient strategy without any templates or reducing gases has been designed to fabricate multi-core yolk–shell Co@C nanospheres by high temperature carbonization. The results showed that Co3O4 was completely reduced by the carbon shell to metal cobalt at temperatures above 750 °C. This unique multi-core yolk–shell structure with shell of 600 nm and multiple cores of tens of nanometers can provide sufficient interface and space to reflect and scatter electromagnetic waves. At the same time, the metal cobalt layer and carbon layer provide magnetic loss ability and dielectric loss ability, respectively, making the composite show good wave absorption performance. The minimal RL value of samples carbonized at 750 °C reaches −40 dB and the efficient absorption band reaches 9 GHz with the thickness ranges from 2–9 mm. Therefore, this is a facile, effective and economical strategy to prepare yolk–shell structure, which provides a new idea for the preparation of microwave absorption materials.

“…Those waves can negatively interact with other equipment, affecting their performance. [24][25][26] Therefore, materials able to attenuate those waves are one of the new major improvements under assessment in the polymer industry. [27][28][29] Among several additives for polymeric composites, Fe 3 O 4 and other iron-based nanoparticles present high potential as fillers for developing EM absorbing polymeric materials because they are inexpensive, non-toxic, exhibit paramagnetic properties and are able to interact with EM waves due to their magnetic properties.…”

Cost-effective polymeric composites were successfully prepared by melt blending granitic quarry waste (GQW) with high-density polyethylene (HDPE). The GQW is a waste generated during the production of manufacture fine aggregates (MFA) from crushed gneiss rock and contains significant amount of mica with iron in its structure. Different sieving and milling procedures were employed. The materials were characterized by mechanical and dynamicmechanical properties and scanning electron microscopy. Moreover, the influence of the GQW on the microwave absorbing properties in the X-band frequency range was investigated. The presence of mica and iron compound in the GQW provides a dual function to the filler: toughening agent with microwave absorbing capacity. Indeed, the addition of 5 wt% of GQW previously sieved and milled by dry or wet-grinding approach resulted in composites with outstanding toughness, modulus and elongation at break. Simulated RL studies revealed electro-magnetic attenuation of À25 dB at 8.7 GHz. Such successful use of a waste generated in the production of a concentrate (MFA) not only contributes to the economics of the quarrying operation, but also to its environmental sustainability, since it replaces disposal of this product, which could lead to dust emissions, given its fine size and low moisture content.
