Electromagnetic Wave Absorbing Properties and Structures of Composites

Dear Colleagues,

Carbon-based composites are a kind of electromagnetic wave (EMW) absorption materials that have been widely studied. Additionally, the carbon components can be roughly divided into graphene, carbon fiber, carbon nanotubes, carbon black and other materials. Normally, a single carbon material tends to cause a "skin effect" due to its high electrical conductivity, which causes a large number of EMW to be reflected on the surface of the carbon material, resulting in negative EMW absorption properties. Based on this, surface modification treatment, compounding, structural design and other methods are often used to achieve impedance matching, thereby improving the EMW absorption performance of carbon materials. Among them, carbon-based composites are considered as potential candidates for high-performance EMW absorption due to its synergistic loss mechanism and diverse composition and microstructural designs. At present, the main challenge is to develop carbon-based composites that meet harsh conditions (such as high temperature resistance, corrosion resistance, etc.), facile preparation process, and high yield.

The purpose of this Special Issue is to provide an international platform for academic exchange on the design, preparation, characterization and application of carbon-based composites, thus promoting the development of carbon-based composites in the field of high-performance EMW absorption.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
