Facile preparation of C/MnO/Co nanocomposite fibers for High-Performance microwave absorption

The excellent electromagnetic wave absorbing properties of carbon fiber composites: the effect of metal content

“…1,2 Absorbers could convert EM energy radiated to the surface into heat energy, attenuate harmful EM waves and effectively suppress EM pollution. 3,4 An outstanding EM absorber should have low cost, small thickness, light weight, wide bandwidth, and strong absorption to improve EM absorption efficiency while maintaining a simple manufacturing process. [5][6][7] Due to solid attenuation characteristics caused by magnetic loss capability, traditional magnetic metals are also widely used in EM absorption.…”

“…[5][6][7] Due to solid attenuation characteristics caused by magnetic loss capability, traditional magnetic metals are also widely used in EM absorption. 8,9 For example, with the synergistic effect of dielectric and magnetic losses, Guo and his coworkers synthesized rod-like ZnO@Fe core-shell composites, which achieved a minimum RL of −48.0 dB at 1.5 mm. 10 Li et al prepared tadpole-like hollow Fe@SiO 2 @C-Ni composites, 11 which exhibited a broad effective absorption bandwidth of 13.1 GHz and a minimum RL value of −45.2 dB.…”

A freestanding 3D heterophase tungsten disulfide-based aerogel as an ultrathin microwave absorber in the Ku-band

“…Generally, the EAB is defined as RL less than −10 dB, representing that more than 90% of the EMW is absorbed. 34 Overall, the absorption properties of GCW-1T were superior in all aspects, including absorption intensity and thickness. Specifically, the thickness (d) of GCW-1T was merely 1.15 mm, corresponding to an RL min value of −56.63 dB (Fig.…”

Highly Breathable and Abrasion-Resistant Membranes with Micro-/Nano-Channels for Eco-Friendly Moisture-Wicking Medical Textiles

“…The control membranes showed outstanding breathable performance (489 mm/s) because of the porous structure of the microfiber. However, the micro-/nano-fibrous membranes demonstrated decreased breathability, owing to the increment of the accumulating density and channel length [ 13 , 32 ]. Notably, the breathability results showed that air permeability with a pressure drop of 200 Pa was twice as high as that of the breathability results with a pressure drop of 100 Pa.…”
