Synthesis of flower-like CuS hollow microspheres based on nanoflakes self-assembly and their microwave absorption properties

Abstract

The flower-like CuS hollow microspheres exhibit the advantages of strong absorption, thin thickness, wide absorption band width and lightweight.

Performance enhanced electromagnetic wave absorber from controllable modification of natural plant fiber

“…58 According to the equation, Cole-Cole plots should be shown as a semicircle, and a Cole-Cole semicircle represents a Debye relaxation process. 59 In Fig. 5, it can be clearly seen that ACR has much overlapping and distorted semicircles than that of CR and FCR, in other words, CR and FCR has fewer relaxation processes when in contrast with the activated ACR, this result agrees well with the foregoing interpretation of 3 0 and 3 00 .…”

Graphene‐Like Multilayered CuS Nanosheets Assembled into Flower‐Like Microspheres and Their Electrocatalytic Oxygen Evolution Properties

“…As an earth‐abundant mineral, copper sulfide (Cu x S, x=1–2) has many potential applications in different fields, such as catalysis, anticancer and antibacterial, superconductor, biosensors, nematic liquid crystal, microwave absorption, UV protection and electromagnetic interference shielding, energy conversion and storage, etc. However, most Cu‐based catalytic showed quite high overpotentials in the OER systems .…”

Construction and Microwave Absorption Properties of Core@Double-Shell Structured Fe3O4@Polyaniline@MnO2 Nanospheres

“…First, the multi-interface polarization e®ect is formed by Fe 3 O 4 core, PANI and MnO 2 shell, which play a signi¯cant role in the EMW attenuation. 42,43 Meanwhile, the electromagnetic parameters demonstrated that the coated MnO 2 shell can adjust the permittivity to improve the degree of impedance matching for FPM nanospheres, which make EMW enter the interior of the material as much as possible and enhancement of the microwave absorbing performance. 44 In addition, it can be found that FPM displays superior dielectric loss to the others, which also can enhance the RL properties.…”
