Special Issue Information

Dear Colleagues,

In recent years, hybrid porous films have gained increasing interest in terms of addressing the needs of modern day technological challenges, as they exhibit highly versatile features, including a high surface area/volume ratio, allowing for enhanced interaction with external reagents, excellent loading capability, high structural stability and improved adhesion, a higher number of active sites, selective permeability, shorter electron/ion transport paths, etc.

This Special Issue of Coatings is focused on recent advances in the approaches employed for the synthesis of hybrid porous films, their characterization, and their properties for varying research fields, such as photocatalytic self-cleaning, antimicrobial activity, UV protection, thermal insulation, electrochemical conversion, energy storage, sensing, and photovoltaics. Other fields of application of porous materials, such as electrode material in energy storage devices, wastewater treatment, and carbon dioxide capture, are welcomed.

It is my pleasure to invite you to submit reviews, regular research papers, and communications to this Special Issue, entitled Recent Advances in Porous Films, 2nd Edition.

Dr. Alina Pruna
Guest Editor

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.

Al2O3/TZ-3YS coatings developed by suspension plasma spraying were studied in the present work. Mechanical and thermal characterization was realized to evaluate the suitability of thermal barrier coatings. In addition, SiC particle reinforcement was evaluated for its effect on the mechanical properties of the coating. The problem with SiC reinforcement is its high melting point that causes a large amount of unmolten material to be deposited on the coating. One possible solution followed in the present study consists of including fructose as an additive in order to modify the suspension characteristics. The results conclude that the use of fructose as an additive increases the mechanical and thermal properties (from 1.0 to 1.6 W/m·K), since the microstructure is modified, and results in a lower porosity (17%) compared to the SiC coating (25%).

This paper presents the results of investigations of optical scattering phenomena in porous silica films. SiO2 films were prepared by the sol-gel method and deposited on polished silicon wafers by the dip-coating technique. Fabricated films were studied using integrating sphere reflectometry, spectroscopic ellipsometry, atomic force microscopy, scanning electron microscopy, and angular resolve scattering. The spectral characteristics of the refractive and extinction indices and scattering extinction coefficients are presented. Additionally, the depolarization of reflected beam from samples was measured. The tested films were characterized by a thickness of 500 to 900 nm, a porosity of 50%, and refractive indices of less than 1.24. The observed depolarization of light reflected from SiO2 films resulted from surface and bulk scattering. This phenomenon resulted from the presence of surface and closed pores located in the bulk of SiO2 film. Full article
