Three dimensional porous MXene/CNTs microspheres: Preparation, characterization and microwave absorbing properties
In this paper, a simple ultrasonic spray technology is used to assemble one-dimensional (1D) carboxylated carbon nanotubes (C-CNTs) and two-dimensional (2D) Ti3C2Tx MXene nanosheets into three-dimensional (3D) porous MXene/C-CNTs microspheres (MCM). After vacuum carbonization, C-MCM with excellent microwave absorbing properties are obtained. It finds that the synergy of MXene and CNTs makes C-MCM have good impedance matching and microwave attenuation capabilities. Under the best mass ratio (MXene: CNTs = 3:1) and filler content (30%), the minimum reflection loss (RLmin) is −45 dB@10 GHz, and the corresponding matching thickness is 2.7 mm. When the thickness is 1.9 mm, the effective absorption bandwidth (EAB) reaches 4.9 GHz. By adjusting the thickness of the absorber, almost all electromagnetic waves in the C, X and Ku bands can be completely absorbed. Therefore, C-MCM provides a new way to manufacture electromagnetic wave absorbers with light weight, thin thickness, high efficiency and broadband.
期刊介绍：
Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
