The study fundamentally investigates the evolution of these surface properties from the instant the particles are coated. Six chemical agents have been used on near-spherical glass beads and the changes in surface profiles monitored. Surface roughness was quantified using the power spectral density method and the surface thickness of the coatings was determined by a new technique which involved calculating the change in the representative radius of asperity. Results showed that the coating process altered the surface roughness and thickness of particles irrespective of chemicals used. The time-dependency of the coating process is illustrated and it was observed that fluctuations in both surface roughness and thickness lessened after a time period of 30 min. Depending on the chemical agent used, either an overall roughening or softening was recorded at 60 min and the values of surface thickness showed increases between 71 and 256 nm. By analyzing the evolution of surface roughness and thickness at the particle level following coating, this study demonstrated the intricate link between surface properties and chemistry in inducing functional properties on particles.</p><h3>Graphical Abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":48804,"journal":{"name":"Journal of Coatings Technology and Research","volume":"20 5","pages":"1795 - 1800"},"PeriodicalIF":2.3,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-023-00798-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"7183716","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}

Many efforts are undertaken to lessen its impact and financial losses. One of the promising methodologies is application of antibiofouling coatings to minimize biofouling, and the best results were observed with a superhydrophobic coating. Ample literature reviews on superhydrophobic coating have shown biofouling inhibition on the surface due to high wetting angles similar to the phenomenon on a lotus leaf. The hydrophobic coating can be deposited using multiple techniques such as electroless plating, chemical vapor deposition (CVD), sol–gel, and electrodeposition. In this review, an effort has been made to encompass such experimental work under a single domain and compare the effectiveness of each coating. In addition, mechanical properties and surface characteristics such as wetting angle, surface energy, and morphology were also discussed for various types of polymeric coating. Similarly, the application of nanoparticles such as ZnO, SiO<sub>2</sub>, TiO<sub>2</sub>, and CeO<sub>2</sub> was found to improve the substrate's mechanical properties, the durability of coatings, improvement in wear properties, adhesion, interlaminar cohesion, and increased wetting angle and above all, improve superhydrophobicity. These improvements are compared for various nanoparticle integrated coatings. In addition, other novel approaches to prevent marine biofouling by various polymer-based coatings such as superhydrophobic, foul-release, and foul-resistant coatings are discussed in this paper.</p></div>","PeriodicalId":48804,"journal":{"name":"Journal of Coatings Technology and Research","volume":"20 5","pages":"1499 - 1512"},"PeriodicalIF":2.3,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-023-00773-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"7183839","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}

Here, alkyd/styrene acrylic waterborne hybrid polymers were synthesized in the presence of monomers, water, emulsifiers, and an initiator by using synthesized alkyd resins at 0%, 5%, 10%, and 15% ratios based on the total monomer ratio. A mini-emulsion technique and a semi-batch polymerization method were used to synthesize the latexes. Two different biosources, tall oil fatty acids (TOFA) and hemp seed oils (HSO), were used to synthesize the alkyd resins. Synthesized waterborne hybrid latexes and their films were analyzed by using FTIR, NMR, particle size, MFFT, TGA, DSC, CA, AFM, and mechanical tests. It was determined that the type and concentration of the alkyds affected the viscosity, particle size, <i>T</i><sub>g</sub> and MFFT values, and appearance. It was also identified that alkyd incorporation took place with grafting and that the alkyd concentration was particularly effective in increasing the particle size. In addition, experiments were carried out on waterborne paint systems for exterior paint by using synthesized hybrid polymer emulsions. It was observed that the alkyd content was not effective in changing the paint color in hybrid latexes.
