Special Issue Information

Dear Colleagues,

Thin film technologies have been developing for many years. Research on and use of these nano- or microscale films has become very popular in recent decades in many research fields, such as in solar cells, optical sensors, display, and medical applictions. Furthermore, the processes of thin films have also been well developed, for example, sol–gel, thermal evaporation, chemical vapor deposition, and sputter technology.

This scope of this Special Issue aims to cover recent developments and the latest research advances in the field of functional optical thin film production, characterization, and application to photonics, optical sensors, optical fibers, solar cells, and green energy production. Authors are invited to submit their papers on optical sensors, energy harvesting devices, solar cells, and any device based on novel fuctional thin film materials. We kindly invite authors to submit a manuscript(s) to this Special Issue on experimental processes, opitcal property measurement, and theoretical and practical analysis of carrier transport and optical device applications.

In particular, the topic of interest includes but is not limited to:

  • Novel optical functional materials;
  • Flexible substrate and their optoelectronic applications;
  • Mechanical properties of thin films;
  • Fabrication, processing, and properties of optical thin film devices;
  • Optical fiber application;
  • Functional and conductive polymer thin films;
  • Structural characterization of functional thermoelectric thin films.

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.

A large-area spray coating process is introduced to efficiently apply a graphene/Cu/cellulose composite on a flexible glass substrate. The dispersion characteristics of nano-additives are measured and the Tyndall effect observed. The characteristics of the composite coating such as the film thickness, surface roughness, water contact angle, and lubricating characteristics are measured. The tribological properties of the composite coating are measured using a ball-on-disk. The wear width of the abrasive parts, as well as the wear and friction coefficient of the grinding balls, are investigated. Adding graphene/Cu helps to improve the anti-wear ability of cellulose. The transfer layer was observed using the Raman spectroscopy and mapping technology. Finally, the lubricating mechanism is discussed, and the wear mechanism is proposed. Nanoparticles existed in the wear track as the third-body particles and improved the load capacity of the composites. The wear mechanism of the composites is discussed in terms of the worn surfaces and the analysis of the transfer film with the third-body approach. Full article
