However, the molecular weight of polyacrylate increased significantly, and the ratio of monomers in the polymer was gradually close to the feeding ratio. Furthermore, the addition of OATP led to long and large-sized latex particles, as well as a decrease in the viscosity and chemical stability of latex, but the thermal stability, pencil hardness and adhesion of latex films were improved. For optimal performance, a suitable amount of OATP addition was 0.6 mass%.

Consequently, measurement of residual stresses in thin films/coatings is of great importance to ensure their reliability in applications. Instrumented indentation, as a sophisticated micro/nano scale testing technique, proves highly effective for measuring residual stress in thin films/coatings due to its exceptional resolution and non-destructive characteristics. This review provides a comprehensive discussion and summary on the current instrumented indentation models for determination of residual stresses, including their advantages and limitations. Furthermore, the trends for future development and possible challenges were also given. For the current models, challenges mainly originate from preparing stress-free thin film/coating samples as reference samples, determining the directionality of non-equibiaxial residual stresses, as well as eliminating the influence of substrates on the measurement accuracy. Thus, there is an increasing demand to establish an instrumented indentation model capable of decoupling substrate effects and accurately measuring non-equibiaxial residual stresses in thin films/coatings without using reference samples.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 2","pages":"581 - 603"},"PeriodicalIF":2.3,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622157","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}

Polyethylene glycol (PEG) is commonly used as the hydrophilic block, but PEG experiences rapid autoxidation which limits its lifetime. Alternatively, zwitterions are protein-resistant and have an ultra-low fouling surface that can bind water molecules stronger than PEG. In this study, the successful synthesis of block copolymers of hydrophobic poly(dimethyl siloxane) (PDMS) and four different hydrophilic zwitterionic monomers was carried out. The monomers were also successfully homo-polymerized. The eight polymers based on sulfobetaine methacrylate (SBMA), sulfobetaine methacrylamide (SBMAm), methacrylate phosphocholine (MPC), or carboxybetaine methacrylate (CBMA) were incorporated as a surface-modifying additive into a polyurethane (PU) coating system to investigate the fouling resistance and fouling-release properties of the surfaces. The goal of this study was to determine which zwitterion copolymerized with PDMS produces the best-performing surface for FR purposes. Antifouling (AF) and fouling-release properties were examined through laboratory assays of three common marine fouling organisms: bacteria, algae, and barnacles. Detailed surface characterization was also conducted to investigate the heterogeneity of the surfaces. It was determined that the coatings containing the zwitterionic polymers improved the FR/AF properties compared to the control. The SBMA and CBMA zwitterionic polymers appeared to improve properties the most. For example, the incorporation of the PDMS-SBMA triblock copolymer reduced the barnacle adhesion from 0.58 to 0.19 MPa.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 3","pages":"951 - 969"},"PeriodicalIF":2.3,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896704","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}

Since some conventional coatings may require high temperatures but sol–gel coating can be completed at low temperatures, it is an easy coating technique for adding antimicrobials to polymeric surfaces. Various antimicrobial compounds used in sol–gel coating preparation have two categories: 1) Chemical compounds such as TiO<sub>2</sub>, Ag, ZnO, CaO, Si, MgO, Au nanoparticles and boron nitride, biocides, hydroxyapatite, and 2) natural compounds such as bioactive liquids and curcumin. Antimicrobial compounds act as a mechanism for forming the reactive oxygen species (ROS), reducing the potential of DNA to duplicate itself, and tRNA interaction with the ribosome is suppressed, disrupting antimicrobial enzyme activity, releasing of ions, preventing bacterial adhesion, and modulation of microbial gene expression. Antimicrobial sol–gel coatings can be applied to the film substrate by dipping, spraying, or spinning processing before gelation. Numerous uses, including textiles, biomedical applications, packaging, glass substrates, metals like silver, copper, zinc, and nickel, and the avoidance of biofilm development, have made application of antimicrobial sol–gel films. Nonetheless, it is frequently utilized in the textile sector to stop microbiological contamination, shield biofouling, and lessen perspiration odor.
