Special Issue Information

Dear Colleagues,

We are pleased to announce the launch of a Special Issue dedicated to the exploration of "Advances in Polymer Coatings for Industrial Applications: Innovations in Sustainability, Performance, and Processing". The aim of this Special Issue is to delve into the dynamic landscape of polymer coatings for various industrial applications, with a focus on driving sustainable practices, enhancing performance metrics, and innovating processing techniques.

Polymer coatings stand as integral components across diverse industrial sectors, from protecting cars to making electronics. In this Special Issue, we aim to capture the breadth and depth of advancements in polymer coatings, spanning applications in automotive manufacturing, construction, packaging, electronics, packaging, and beyond. As industries increasingly seek eco-friendly solutions without compromising on performance, this Special Issue will showcase pioneering research and practical implementations aimed at reducing environmental footprints while meeting industrial demands. Furthermore, as industrial processes evolve, the methodologies for coating application and processing must also evolve. From automated coating systems to novel deposition techniques, this Special Issue will explore the latest innovations in processing technologies for maximizing the efficiency of coatings.

The current hot topics that will be covered in this Special Issue include but are not limited to the following:

  • Theoretical and experimental research, knowledge, and new ideas on polymer-based films and coatings;
  • Preparation and characterization of polymer-based coatings;
  • Understanding the degradation mechanisms of coatings;
  • Recent trends in coating synthesis and application techniques;
  • Sustainable coating formulations;
  • Investigating the role of polymer coatings in addressing specific industrial challenges such as corrosion, wear, antimicrobial properties, barrier properties, temperature resistance, etc.

We look forward to both original research papers and review articles for the aforementioned topics that will contribute to the multidisciplinary domains of novel coatings.

This study introduces a novel paper coating approach using modified zinc oxide (ZnO), providing a comparison with conventional materials used in the paper industry. The research focused on determining the concentration for effective microbial growth inhibition and evaluates the impact of different ZnO types on coated-paper properties, including antimicrobial activity, surface morphology, tensile strength, and water absorption. Specifically, ZnO microparticles (ZnOws), ZnO nanoparticles (ZnOnp), and modified ZnOnp (ZnOnp-CaCO3, with a core–shell structure composed of calcium carbonate [CaCO3] and nano-zinc oxide) were incorporated into coating formulations at varying concentrations (0 × MIC, 1 × MIC, 2 × MIC, and 3 × MIC, based on minimum inhibitory concentrations [MICs]). The results demonstrated that among all tested microorganisms, ZnOnp-CaCO3 showed the lowest MIC values. ZnOnp-CaCO3-coated paper exhibited superior antimicrobial activity against both Gram-positive and Gram-negative bacteria, as well as fungi, outperforming ZnOws and ZnOnp. At 1 × MIC, %inhibition for E. coli, S. aureus, and A. niger were 98.3%, 99.1%, and 90.8%, respectively. Additionally, ZnOnp-CaCO3 coatings caused minimal color change in the paper compared to the other ZnO variants. The coating did not negatively impact the mechanical properties of the paper across all ZnO types and concentrations. Water absorption tests showed increased hydrophobicity with higher ZnO content, with ZnOnp and ZnOnp-CaCO3 exhibiting greater reductions in water absorption than ZnOws. Overall, ZnOnp-CaCO3 showed strong potential as an antimicrobial agent for paper surfaces, making it ideal for packaging and hygiene products. By partially replacing ZnOnp with inexpensive CaCO3 core particles, ZnOnp-CaCO3 delivers enhanced performance, reduced costs, and greater sustainability for large-scale applications. Full article

Dust deposition poses a significant challenge in the implementation of photovoltaic panels (PV) especially in hot and dusty environments, such as the Middle East and North Africa (MENA) region. This issue leads to progressive degradation of PV efficiency and output power. In this context, this research work aims to improve PV performance by developing self-cleaning sprays as a preventative solution. Different concentrations of SnO2 and TiO2 nanoceramics were dispersed in isopropyl alcohol solvent to reduce the mixture’s viscosity and facilitate smooth spraying on solar panels, whose efficiency was continually assessed in outdoor conditions. Although less commonly used for this application, the nano-SnO2 was selected for the purpose of enhancing the surface hydrophobicity, whereas nano-TiO2 was included for its favorable photocatalytic properties. Polydimethylsiloxane (PDMS) oil, known for its self-cleaning characteristic, was served as the base material in the developed sprays. The described blend of materials represents a novel combination. The results indicated that 2.5% nano-SnO2 and 2.5% nano-TiO2 in PDMS oil enhanced efficiency by 5.4% compared to a non-sprayed panel after five weeks of outdoor exposure. This efficiency gain was experimentally justified and attributed to the spray’s ability to achieve a water contact angle (WCA) of 100.6°, forming a hydrophobic surface conducive to self-cleaning. Further characterization results, including photocatalysis and zeta potential have been gathered and analyzed. Full article
