In this work, materials with different chemistry and morphology were added to an acrylic dispersion to create hydrophobic surfaces using a non-fluorinated coating simple strategy for glass substrates. Results showed that materials with more complex morphology, namely the spherical shape of silica nanoparticles, and the needle-like and prism-like structures of zinc oxide, imparted the glass with higher water contact angles. All coatings prepared displayed self-cleaning features and good adhesion to the glass substrate. Coatings comprising silica nanoparticles, zirconia and alumina modified with HDMTS were the best ones to prevent ice formation. In terms of chemical stability, all the coatings resisted acidic conditions close to acid rain pH and solvents with mild polarity. Therefore, the coatings proposed hold great potential to expel dust contaminants and prevent ice formation of photovoltaic devices, increasing their lifetime and power generation efficiency.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"21 6","pages":"1907 - 1919"},"PeriodicalIF":2.3,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-024-00936-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141119478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we proposed a simple strategy using dispersant Disuper S9100 as dispersant and polyethylene glycol (PEG) as wetting agent to achieve single-dispersed TiO<sub>2</sub> particles with long storage stability and good re-dispersibility in low viscosity systems. The effect of PEG average molecular weight on the stability and re-dispersion performance of TiO<sub>2</sub> dispersion was investigated. Our study showed that PEG molecules were adsorbed on the surface of TiO<sub>2</sub> particles through hydrogen bonding, and synergized with nonionic polymeric dispersant Disuper S9100 to increase the steric hindrance between the particles. Due to the different adsorption conformations of PEG molecules, the dispersion stability and re-dispersibility of TiO<sub>2</sub> particles was gradually improved with increasing PEG average molecular weight. However, PEG molecules with excessively high molecular weight weakened the dispersion stability of TiO<sub>2</sub> particles.

The main reason relies on their low surface energy, which reduces the affinity between the polyolefin surface and the chosen adhesive. To tackle this problem, the most commonly used solutions are physical surface treatments, such as plasma, corona, and flame, which introduce hydrophilic moieties on the plastics surface, thus increasing their surface energy. These approaches require special setups, are unspecific, and can induce material degradation. Furthermore, they provide a transient solution, making the storage of pretreated substrates not recommended. In this work, we developed an easy-to-apply primer for durable bonding of adhesives on PE and PP, as robust alternative to physical treatments. Our primer contains a surface-anchoring moiety and an adhesive-binding group to covalently react with the polyolefin substrate and with the glue. As a surface-anchoring moiety, we chose the perfluorophenylazide (PFPA), which is known to undergo a C–H insertion reaction upon UV activation, while as adhesive-binding groups, we selected OH functions, which can covalently react with the most common commercially available glues. When these two features (i.e., PFPA and OH) are combined in a single molecule, the reaction with the substrate does not occur and the molecule is only physisorbed, inducing no adhesion improvement. Chemisorption only occurs with bicomponent formulations, comprising a hydrophobic trifunctional PFPA and a polymer bearing OH and PFPA groups. Those induced improved adhesion on PP compared to the golden standard plasma with polyurethane-based and two-component epoxy adhesives. Storing the coated substrates at room temperature for up to two months did not alter the adhesion performance, thus further ascribing the developed primers as a promising alternative to plasma treatment.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"21 6","pages":"1921 - 1930"},"PeriodicalIF":2.3,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-024-00938-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the efficacy and overall effectiveness of solar PV cells are significantly affected by various aspects, including ecological conditions and operation and maintenance practices. These factors directly impact the outcome, energy utilization efficacy, productivity, and lifespan of the PV cells, ultimately influencing the economic aspects of power generation. A highly effective method for mitigating ecological factors is applying a self-cleaning and antireflective coating, which utilizes micro–nano structures and surface wettability to facilitate cleaning and enhance light transmission. This study investigates the influence of ecological and operational factors on solar PV cell effectiveness. Further, a brief summary of the basic principles and development of self-cleaning and antireflective coating is presented by examining recent research. The review reveals that soiling, humidity, and temperature negatively influence the performance of PV modules. In humid conditions, dust deposition leads to the formation of adhesive mud on PV cells, resulting in a reduction of power generation by as high as ~ 70%. In addition, it is also suggested that the application of self-cleaning and antireflection coating on PV modules enhances its efficiency by ~ 11% compared to uncoated modules.
