Shape-tunable vanadium selenide/reduced graphene oxide composites with excellent electromagnetic wave absorption performance

The tunable energy gap and distinctive layered configuration of transition metal dichalcogenides (TMDs) has sparked considerable interest in their capabilities for electromagnetic wave absorption. As a significant TMD, vanadium selenide (VSe₂) is characterized by a superior electrical conductivity (1 × 10⁻³ S/m) and an expanded interlayer distance, which are advantageous for electromagnetic wave absorption performance. Nevertheless, the current research on VSe₂ in electromagnetic wave absorption is relatively limited. In this study, flower-like VSe₂ and shape-tunable VSe₂/reduced graphene oxide (rGO) composites were fabricated via a simple solvothermal method, and the effect of their morphology on electromagnetic wave absorption performances was investigated. The VSe₂/rGO composites exhibited remarkable electromagnetic wave absorption properties at a thickness of 2.01 mm, with a reflection loss value (RL) of up to −79.50 dB, and an effective absorption bandwidth (EAB) of 5.2 GHz (1.45 mm). This research has identified a novel approach to the study of TMDs in the field of electromagnetic wave absorption.

期刊介绍： The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
