Special Issue Information

Dear Colleagues,

The Coatings journal is preparing a Special Issue entitled “Recent Innovations in Polyurethane Coatings and Films”.

Polyurethanes (PUs) are a very broad group of polymers that are widely distributed and investigated in the world. According to the results announced by Statista, the global market volume of PUs amounted to 25.7 million metric tons in the year 2022, and there are predictions that this figure will grow significantly in the coming years. PUs’ structure–property relationships are significantly influenced by the applied reagents, molecular structure, composition, obtained molecular weight, presence of microphase separation, crystallinity, new methods of synthesis, addition of micro- or nano-fillers, and more. PUs have good mechanical and thermal properties, good chemical resistance, adjustable surface morphology, and wide substrate suitability, amongst others. Therefore, they have widespread uses, such as coatings, adhesives, elastomers, paints, inks, and so on.

The goal of this Special Issue is to provide a forum for discussion and publish the recent advances and innovations in the field of synthesis and achieving improved properties of PUs. Therefore, the Editors are pleased to announce that this Special Issue is open to submissions and researchers are welcome to participate and contribute their latest and original papers or reviews connected with “Recent Innovations in Polyurethane Coatings and 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.

In this research, the structure, morphology, hydrophobicity and swelling behavior of a polyurethane (PU) network and its composites (PUCs) were examined. PUCs were synthesized by the incorporation of different percentages (0.5, 1 and 2 wt.%) of unmodified or surface-modified TiO2 nanoparticles into a PU network based on polycaprolactone, aliphatic hyperbranched polyester and isophorone diisocyanate. In order to improve interfacial interactions, the surface of the TiO2 nanoparticles was chemically modified with lauryl gallate. The impact of the presence and content of unmodified or surface-modified TiO2 nanoparticles on the cross-sectional and surface morphology, swelling behavior and hydrophobicity of the PU network was assessed by different experiments. The obtained findings revealed that the incorporation of TiO2 nanoparticles brought a more pronounced irregular cross-sectional and rougher surface morphology, better microphase separation, higher values of the equilibrium swelling degree in tetrahydrofuran and toluene, and altered water contact angles compared to the neat PU. Based on the collected results, the practical applicability of the prepared PUCs may be in the area of protective coatings. Full article
