In this work, multifunctional coatings were obtained by combining functionalized halloysite nanotubes (HNT) with an epoxy primer. Fluorine-free coating (EsH) was prepared using a silanized HNT and fluorine-containing coatings (FPH) were obtained by a sol-gel co-condensation of a fluorinated silane and polyhedral oligomeric silsesquioxane (POSS) over activated HNT, thus producing FPOSS@HNT. The coatings were applied over epoxy primer holding different curing conditions. Both, EsH and FPH samples showed superhydrophobicity. The micromechanical properties of the coatings showed viscoelastic-plastic behavior which was sensitive to the curing state of the primer and fluorine presence. The materials were subjected to a slurry erosion test under high speed flow conditions and wettability was used to characterize the surface integrity over erosion-cumulative time periods. FPH coatings showed an outstanding resistance to the high speed slurry erosion.

The emulsion was prepared using commercially available surfactants and free of volatile organic substances (VOCs). The most applicable technology for the production of alkyd-siloxane emulsions is direct emulsification at a temperature of 60°C, and using dynamic light scattering, the hydrodynamic radius of the particles was determined to be 132 ± 38 nm. The resulting emulsion has an aggregative and sedimentation stability during storage up to 3 months; however, the temperature difference causes the destruction of the colloidal system. The curing reaction occurs within 10 min to form a coating containing 95% gel fraction. Emulsion-based coatings have better properties relative to alkyd coatings but are not significantly inferior to coatings from an organo-soluble UV-curable composition. Coatings based on UV-cured materials have shown low chemical resistance, which limits their use in conditions where contact with aggressive liquids occurs. The presence of surfactants in the coating reduces the water contact angle by 4° and increases water absorption by 1.5% relative to coatings based on organo-soluble alkyd-siloxane composition. Sorption studies have shown that the diffusion coefficients of water into the coating from the emulsion and the organo-soluble system have the same values and amount to 8.35·10⁻⁹ cm²/s. The difference in the glass transition temperature of coatings obtained from an emulsion (21.0°C) and a solution (24.2°C), as well as a decrease in heat resistance, indicates a lower degree of crosslinking due to the presence of surfactants in the system. Elemental and morphological analysis showed that there is no phase decay during the process of coating formation, and all elements are evenly distributed over the surface. A comparative analysis of the results of the study with the literature data showed that the obtained emulsion is not inferior in properties to other UV-curable water-based materials.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 3","pages":"1185 - 1205"},"PeriodicalIF":2.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of water-based polyurethane dispersions (WPUCOs) were prepared by incorporating different levels of branched flexible castor oil into the formulation. The hydroxyl content provided by castor oil accounted for 0%, 10%, 20%, 30%, 40%, and 50% of the total hydroxyl content provided by castor oil and the alkyd polyol, and these variations were designated as WPUCO-0, WPUCO-10, WPUCO-20, WPUCO-30, WPUCO-40, and WPUCO-50, respectively. The WPUCOs were synthesized using an alkyd polyol, castor oil, 4,4'-dicyclohexylmethane diisocyanate (H₁₂MDI), and 2,2-dimethylolpropionic acid as key components. These WPUCOs were analyzed using Fourier transform infrared spectroscopy, laser diffraction particle size analysis, and rheological measurements. Waterborne polyurethane-amino resin curing films based on the above-mentioned WPUCOs were then fabricated and characterized through thermogravimetric analysis, differential scanning calorimetry, contact angle measurements, water absorption tests, and gel content determination. Furthermore, waterborne polyurethane-amino baking coatings were also formulated using WPUCOs to evaluate their performance. The results showed that yellowish WPUCOs were successfully prepared. The viscosity and particle size of WPUCOs are observed to rise as the proportion of castor oil in the formulation increases. Among all formulations tested, WPUCO-30 exhibited superior film properties and coating performances. For instance, the water absorption ratio of the resulting waterborne polyurethane-amino resin curing films based on WPUCO-30 was only 2.81%, while achieving a gel content of 93.85%. Additionally, the pencil hardness and impact resistance values for the waterborne polyurethane-amino baking coating based on WPUCO-30 reached 3H and 50 kg·cm, respectively, and glossiness measured at a 20° angle reached 89.6 GU. Moreover, the number of times the coating could withstand acetone scrubbing reached up to 12,408 times. Therefore, castor oil containing three-chain structures can be effectively utilized to enhance the performance characteristics of waterborne polyurethane-amino resin baking films/coatings.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 4","pages":"1473 - 1487"},"PeriodicalIF":2.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a powerhouse for an array of applications including electric vehicles, portable electronics, and grid storage, the optimization of LIBs is a subject of robust and ongoing scientific inquiry. One of the critical challenges faced in LIBs is the formation of lithium dendrites—a type of crystal that grows on the lithium anode during the charging process. These dendritic structures can pierce the battery's separator, leading to a short circuit, and in worst-case scenarios, fires, or explosions. A promising avenue toward this goal lies in the development and application of innovative coating techniques. These processes can provide a protective layer on the anode, curtailing the growth of dendrites, and thereby enhancing battery life and stability. Thus, this review summarizes the various coating techniques which include physical vapor deposition, atomic layer deposition, and electrochemical deposition. This comprehensive review will delve into the varied coating techniques that have been proposed and implemented to address the dendrite problem. By investigating and comparing these strategies in depth, this article aims to provide a holistic understanding of current mitigation methods and a glimpse into the future trajectory of lithium-ion battery research.

Concentration of PLGA solution, dip speed, number of coatings, dwell time, and drainage time were evaluated for their influence on coating thickness and defects. The parameters were optimized to achieve a coating thickness between 10 and 20 microns with minimal defects. Coating uniformity was primarily influenced by solution concentration, where increasing the solution concentration enhanced the uniformity. Through Face-Centered Central Composite Design experiments, the study found that coating thickness increased with increased dip speed, decreased number of coats, increased dwell time, and decreased drainage time.
