Facile synthesis of hierarchically porous rGO/MnZn ferrite composites for enhanced microwave absorption performance

Investigating the Effect of Changing the Nanostructure of the Core in the Core–Shell Assembly for High-Efficiency Electromagnetic Wave Absorbers

“…For a given t m in which the f m satisfies this equation, the phase difference between the electromagnetic wave reflected by the metal-absorber interface and the air-absorber interface is 180°. 4,21,28 The corresponding simulations between absorber thickness and peak frequency of BF2@MoS 2 under this model are displayed in Figure 9. This figure indicates the matching thickness coincides with the experimental results.…”

“…Two-dimensional materials with ultra-thin-layered structures are convenient for constructing excellent EMW absorbers due to their large specific surface area and excellent electronic properties. − One of the most important and widely studied monolayer materials is molybdenum disulfide (MoS 2 ), which has excellent dielectric properties, unique morphology, and small band gaps. − Wang et al prepared palygorskite/MoS 2 nanocomposites by a hydrothermal method. The suitable minimum reflection loss (RL min ) was obtained at the thickness of 2.28 mm .…”

Tailored design of p-phenylenediamine functionalized graphene decorated with cobalt ferrite for microwave absorption

“…Firstly, the CoFe 2 O 4 was fabricated by a solvothermal method according to our previous report with some modication. 28 In a typical procedure, FeCl 3 $6H 2 O (5 mmol), CoCl 2 $6H 2 O (2.5 mmol) and polyvinylpyrrolidone (K30, 0.2 g) were dissolved into 40 mL mixed solution containing same-volumetric ethylene glycol and diglycol with magnetic stirring for 40 min, then urea (40 mmol) was added. The mixture solution was sealed into Teonlined autoclave (50 mL) and maintained in 180 C for 20 h. The CoFe 2 O 4 was obtained.…”

Application of the Zn0.5Mn0.5Fe2O4–PMMA nanocomposite for efficient removal of complex organic pollutants

“…However, PMMA is typically a non-conducting and nonmagnetic polymer. In contrast, zinc manganese ferrite exhibits a high dielectric constant (e 1 ) and low dielectric loss (e 2 ), 29 and this combination has been implemented in cobalt-based ferrite as xCoFe 2 O 4n -PMMA for industrial applications, 26,30 but the utilization of Zn-MnFe 2 O 4 NCP-PMMA is not yet explored. Therefore, by incorporating Zn-MnFe 2 O 4 NCPs into PMMA, it becomes possible to integrate electrical and/or magnetic properties into soft PMMA matrices.…”
