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 TiO₂, 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. This paper presents and discusses the various antimicrobial compounds with their antimicrobial mechanism and various applications of coatings obtained from sol–gel.</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 2","pages":"527 - 548"},"PeriodicalIF":2.3,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622104","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}

Color parameters and infrared spectra were measured after defined exposure times and normalized to the irradiation doses. Color changes of an industrial standard with an orange pigment (ORWET) were found to depend for both artificial and natural weathering tests predominantly on irradiation dose. This confirms that the spectral power distribution of the lamp/filter configuration proposed in NP matches sufficiently well to both the sunlight spectra in Florida and Stuttgart. For a melamine-based standard crack coat, crack initiation was found only for NP and the late stage of ZS. For all coating systems studied, characteristic band intensities of infrared spectra and/or color parameters for the two protocols and from natural weathering at the related outdoor sites were shifted along the time axis to merge to master plots. To differentiate between thermally activated, photo-initiated, and hydrolytic degradation, the shift factors were plotted versus inverse annual- or cycle-averaged temperatures including irradiation ratios and averaged humidity ratios. Despite the different reaction mechanism for the acrylic component in the silicone resin/acrylate and the polyurethane coating, a dominance of thermally activated degradation was evident for both. The melamine-based binder showed coupled degradation mechanisms (photo-induced and thermally activated complimented by moisture effects). The use of irradiation doses, cycle-, and annual-averaged temperatures together with cycle- and annual-averaged humidities for data analysis provided simple possibilities for comparison of protocols and weathering sites and a rough differentiation between degradation mechanisms.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 2","pages":"739 - 761"},"PeriodicalIF":2.3,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-024-01005-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622182","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}

Higher-viscosity inks imparted greater color density to the print; this was assessed as being due to both the inherently higher viscosity of the ink reducing penetration into the substrate and the higher pigment loading capable of being contained within these inks. While standard-viscosity inks tended to plateau in color intensity as ink coverage was increased, higher-viscosity inks could increase in intensity throughout the entire coverage range on coated white liner. This effect was dependent on the substrate, with the coated white liner exhibiting up to a 67% increase in maximum color density but the uncoated brown liner showing up to a 13% increase.
