“…Chemically modified graphene (CMG), intrinsically known as reduced graphene oxide (rGO) with sp 2 hybridized monolayer carbon atoms, has been used extensively in fabricating electronic devices over the past decades. The rGO nanosheets have high impact features such as high charge carrier mobility (up to 200,000 cm 2 V −1 s −1 ), low energy band π electrons, high electronic conductivity, thermal conductivity, and mechanical stiffness suitable for various applications 8–10 . These nanosheets have giant charge concentration up to 10 13 /m 2 .…”

High performance electromagnetic interference (EMI) shielding materials with ultra‐low density, excellent flexibility with comprehensive nature are highly demanded for wearable electronics, aeronautic, industries, medical, and research facilities. To address these requirements, the metal‐carbon based polymer composites have been fabricated by simple and scalable synthesis techniques. Combining the effect of multiple scattering with absorption, a high shielding efficiency of up to 29 dB for 0.1 mm is achieved. Selective architects of Ag/Cu nanoparticles along with two‐dimensional conducting sheets of MWCNT/rGO form multiple scattering structures in poly(vinylidene fluoride) matrix, prepared by facile solvent cast technique. The paper discusses the preparation of the composites, studies on morphological aspects, and concludes with a study on EMI shielding in the frequency region between 8 and 12 GHz.

Insertion of 2:1 organo-modified phyllosilicate tactoids into rheologically tough thermoplastics has extraordinary potential candidate in oxygen permeability and microstructural toughening. Herein, two commercially abundant clays have been taken for improvement of the thermoplastic's gas barrier property in reasonably low loading. The cause of low loading has been accounted to the usage of maleated polyethylene (MA-g-PE) during the melt mixing tenure. The optimized nanocomposite compression molded film has been tested against uniaxial stretching, which showed a negligible change in the residual permanent set with sacrificing the elongation at break feature. Moreover, nanoindentation was also performed to get the hardness of the sample surface. The flow behavior of the nanocomposites showed thixotropic likely with increasing the frequency. Oxygen transmission rate (OTR) has significantly decreased for tallow amine-modified nanoclay system (cloisite 15A) in compar

Ni x Cu 1−x Fe 2 O 4 nanocrystals were prepared by co-precipitation technique to study the electromagnetic (EM) wave absorption properties. The XRD and SEM results confirm the formation of single-phase cubic spinel structure and reveal that the crystallite size decreases with the addition of Ni content. The vibrating sample magnetometer results showed that the as-prepared material was soft magnetic and have potential applications in magnetic storage technology and field sensors. The dielectric parameters and EM wave absorption characteristics of Ni x Cu 1−x Fe 2 O 4 nanocrystals were studied in the frequency range of 1-18GHz using a vector network analyzer. The permittivity, impedance matching, and EM wave absorption of the materials are significantly improved with the increase in Ni content. The lowest value of reflection loss (R L ) is observed −22.8 dB at 16.09 GHz (R L −10dB, absorption >90%), showing an optimal EM wave absorption performance, which might generate from the synergistic effect between relative permittivity and permeability.
