High-Performance Polymer-Based Dielectrics for Energy Storage

Dear Colleagues,

Polymer-based dielectrics have received increasing attention in electrostatic capacitor field ascribing to their unique characteristics, i.e., high electric breakdown strength, light weight, flexibility, and ease of processing. Nevertheless, their relatively low dielectric constant (generally below 10) remains a critical limitation, leading to unsatisfactory energy density despite excellent breakdown endurance and low loss. To meet the rising demand for compact and integrated electronic systems, improving the permittivity of polymer dielectrics without sacrificing other desirable properties has become a crucial research direction. This Special Issue focuses on recent advances in material design and engineering strategies, i.e., as nanocomposite fabrication, polymer blending, and interface modulation, etc., that aim to break existing performance bottlenecks and accelerate the development of high-energy-density capacitive materials for next-generation power devices.

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. 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.
