Special Issue Information

Dear Colleagues,

In recent years, with the rapid growth of wearable smart devices and next-generation electronics, electromagnetic interference (EMI) induced by microwave radiation becomes a critical issue. As a result, there has been a considerable demand for the creation of advanced shielding materials with high performance that can effectively block and/or reduce interfering signals. EMI shielding materials and their underlying shielding mechanism are regarded as one of most important research frontiers. Numerous materials have been fabricated, and their EMI shielding performance has been explored. Among various EMI shielding materials, polymer-based shields have been more popular because of their properties, such as versatility, excellent processability, broad shielding bandwidth, and low cost. These advantages offer great promise for applications in the EMI shielding industry.

This Special Issue of Polymers on “Advanced Materials for Electromagnetic Shielding” will attempt to capture recent advances in polymer-based shielding materials. It welcomes both theoretical and experimental approaches, covering aspects from the design, synthesis, and fabrication of novel intrinsically conductive polymers or functional filler/polymer composites with EMI shielding capabilities, characterization, characteristics, properties’ integration or regulation, and analysis of shielding mechanisms. Both reviews and original research articles are welcome.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Polymers 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 2700 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.

To meet the comprehensive demand for flexible microwave absorbing (MA) materials, a novel MA rubber containing homemade Polypyrrole nanotube (PPyNT) is produced based on the natural rubber (NR) and acrylonitrile-butadiene rubber (NBR) blends.

To meet the comprehensive demand for flexible microwave absorbing (MA) materials, a novel MA rubber containing homemade Polypyrrole nanotube (PPyNT) is produced based on the natural rubber (NR) and acrylonitrile-butadiene rubber (NBR) blends. To achieve the optimal MA performance in the X band, the PPyNT content and NR/NBR blend ratio are adjusted in detail. The 6 phr PPyNT filled NR/NBR (90/10) composite has the superior MA performance with the minimum reflection loss value of −56.67 dB and the corresponding effective bandwidth of 3.7 GHz at a thickness of 2.9 mm, which has the merits in virtue of achieving strong absorption and wide effective absorption band with low filler content and thickness compared to most reported microwave absorbing rubber materials over the same frequency. This work provides new insight into the development of flexible microwave-absorbing materials. Full article
