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. It is envisaged that wider adoption of higher-viscosity inks can increase both color intensity and printing speed, thus making inkjet more competitive with conventional printing processes.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 2","pages":"715 - 726"},"PeriodicalIF":2.3,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-024-01001-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622107","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}

The findings reveal that the biochar loading position significantly influences the physicochemical properties of the fertilizer. Specifically, biochar incorporated on the outermost layer of the film (BPU-O) exhibits a dense coating with rough surface morphology and high hydrophobicity, thereby demonstrating optimal-controlled release performance.

The exceptional-controlled release performance of BPU-O can be attributed to the oxygen-containing functional groups on cotton stalk biochar. These functional groups, particularly hydroxyl groups, react with residual isocyanates on the polyurethane surface, enhancing compactness and hydrophobicity through grafting and filling effects, thereby, effectively inhibiting water ingress into the core of the fertilizer.
