“…Figure 5c shows the C 0 curves of RGO/SrFe 12 O 19 nanocomposites. while the C 0 is basically unchanged above 9 GHz, while above 9 GHz the C 0 is basically unchanged [34,35]. This implies that the main reasons for the magnetic loss are natural resonance, hysteresis effect and exchange resonance in the range of 2-9 GHz, but eddy current loss accounts for the magnetic loss in the range of 9-18 GHz.…”

AbstractWith the rapid development of electronics and information technology, electronics and electrical equipment have been widely used in our daily lives. The living environment is full of electromagnetic waves of various frequencies and energy. Electromagnetic wave radiation has evolved into a new type of environmental pollution that has been listed by the WHO (World Health Organization) as the fourth largest source of environmental pollution after water, atmosphere, and noise. Studies have shown that when electromagnetic wave radiation is too much, it can cause neurological disorders. And electromagnetic interference will cause the abnormal operation of medical equipment, precision instruments and other equipment, and therefore cause incalculable consequences. Therefore, electromagnetic protection has become a hot issue of concern to the social and scientific circles.

“…During the last decades, polymers and their composites have been continuously displacing the conventional materials, due to their relatively simple processability, low manufacturing cost, and outstanding corrosion resistance . The enhanced physical, chemical, and engineering properties make these materials widely used in the industrial fields, to be specific, the fabrication of the helicopter rotors, wind turbine blades, water blades, aircrafts, sensors, electromagnetic interface (EMI) shielding, and pipelines . In a series of polymers, a segmented copolymer thermoplastic polyurethane (TPU) with hard and soft blocks attracts tremendous attention for both scientific research and industrial applications .…”

A co‐coagulation method combined with hot pressing technique is successfully applied to fabricate thermoplastic polyurethane (TPU) nanocomposites with different contents of carbon nanotubes (CNTs). Obviously, the mechanical and thermal properties of the nanocomposites are improved with increasing the CNT content. In addition, the existence of hydrogen bonding between CNTs and polymer matrix is demonstrated. Furthermore, the influences of impact parameters on solid particle erosion behavior are investigated systematically. The surface roughness and line roughness are also investigated to illustrate the mechanism of solid particle erosion. As elastic nanocomposites, the maximum and minimum erosion rate (ER) occur at 30° and 90°. The ER is relatively small when the impact velocity is at 10 m s−1, then is increased rapidly between 20 and 30 m s−1. As the size of impact particles increases to 300 µm, a rapid increase of ER occurs between 10 and 20 m s−1. All these results indicate CNTs improve the erosion resistance of TPU matrix.

Designing an electrocatalyst by integrating multiple classes of materials is an effective strategy for reinforcing the electrode properties. This study demonstrates a facile electrospinning technique for functionalizing the carbon nanofibers (CNFs) with Nb2O5 co‐catalyst as the support material for platinum nanoparticles. The resultant Nb CNF‐Pt electrode has a sensible Pt loading of 30 µg cm−2 and manifests high catalytic activity towards the oxygen reduction reaction (ORR), methanol oxidation reaction (MOR), hydrogen evolution reaction (HER), and oxygen evolution reaction (OER). The Nb CNF‐Pt outperforms the commercial 20 wt% Pt loaded carbon with high positive onset potential (0.99 V vs reversible hydrogen electrode (RHE)) and half‐wave potential (0.87 V vs RHE) during ORR. It also provides large electrochemical active surface area (94.19 m2 g−1) and mass activity (783.34 mA mg−1) during MOR. Furthermore, the Nb CNF‐Pt electrode demands an extremely minimal overpotential of 37 and 325 mV and a Tafel slope of 38 and 81 mV dec−1 for HER and OER, respectively. The enhanced electrocatalytic activity of Nb CNF‐Pt is attributed to the strong metal–support interaction between Nb2O5 and Pt, resulting in a uniform loading of Pt NPs with reduced particle size and agglomeration‐free distribution.
