Special Issue Information
Dear Colleagues,
Gas sensors play an important role in various fields, such as environmental monitoring, industrial/agricultural process control, and preliminary diagnosis of disease by breath analysis. Polymers are promising gas sensing materials because of their good processability, low cost, and easy chemical modification for selective gas detection. Furthermore, the use of polymers makes sensors more flexible and achieves low power consumption through low-temperature operation, which are advantageous for increasing portability and for applications to IoT technology. However, it has proven difficult to detect gas with a concentration of ppb or less when using polymer-based gas sensors prepared by conventional casting methods.
The performance of gas sensors is related to the gas adsorption/desorption properties of sensing films, irrespective of their sensing mechanism. Gas adsorption properties of polymer films are greatly affected by their nanostructure and morphology, as well as the chemical structure of polymers. Developing structure-controlled polymer films with large surface areas and good gas diffusivity is an effective way to improve gas-sensing properties and fabricate high-performance gas sensors.
Various nanostructured polymer films, such as nanofibers, nanowires, nanorods, nanotubes, spherical particles, and other morphologies, have been reported as gas sensing films. This Special Issue aims to provide an overview of the recent progress and developments in the area of gas sensors based on polymers. Reviews and original research papers dealing with the fabrication of nanostructured polymers, control of film morphology, and their applications in gas sensing fields 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. Sensors 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.
