Special Issue Information
Dear Colleagues,
Carbon nanotubes (CNT) are structures made of carbon often with a diameter in the range of 10 to 100 s nanometers. CNTs have demonstrated exceptional electrical, optical, and thermal properties; in addition, they also have remarkable tensile strength. CNTs are generally divided into two classes, single wall nanotubes (SWNT) and mutliwall nanotubes (MWNT). SWNT consists of a single roll of grephene and MWNT comprises multiple rolled layers of grephene stacked in a concentric configuration. The two most common lattice structures of CNTs are zigzag and armchair, which result in drastically different properties. CNTs have the potential to serve as the next-generation cathode material due to their expectional electrical and thermal conductivity. We are assembling a Special Issue of Coatings to encourage researchers to publish their novel ideas and studies on using CNT for advanced cathode development.
In particular, the topic of interest includes but is not limited to:
- Electron emission characteristics of CNT cathodes;
- Modeling of CNT;
- Field emission characteristics of CNTs;
- CNT for high current applications;
- Outgasing behavior of CNT cathodes;
- Properties of CNT cathodes.

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. Coatings is an international peer-reviewed open access monthly 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
