However, such foods are typically served at high temperatures, and existing packaging materials fail to allow consumers to effectively judge the temperature. This study developed thermochromic, water- and oil-proof cardboard specifically designed for fast food packaging. The coating, consisting of sodium alginate (SA), hydroxypropyl methylcellulose (HPMC), polyvinyl butyral (PVB), and ethyl cellulose (EC), was applied to the cardboard, coupled with a thermochromic material (TC) incorporating crystal violet lactone (CVL), bisphenol A (BPA), and stearyl alcohol. The resultant cardboard exhibited outstanding water- and oil-proof properties. The enhanced oil resistance was attributable to hydrogen bonding between SA and HMRC, as well as cross-linking between SA/HPMC and calcium ions (Ca²⁺) in the base paper. The PVB/EC coating further reinforced the cardboard's waterproofing and mechanical properties through additional hydrogen bonding. In thermochromic tests, the cardboard displayed a significant color change, transitioning from dark blue to colorless as the temperature increased from 30 °C to 55 °C. Overall, this research developed a bamboo-fiber-based food packaging cardboard with superior water- and oil-proof, and thermochromic properties.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109236"},"PeriodicalIF":6.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, pure anti-corrosive coatings are often susceptible to the formation of micropores and cracks during the preparation process and can be easily damaged by external environment factors during service, significantly reducing their protective capabilities. An effective strategy to address this issue is the incorporation of high-aspect-ratio, high stability two-dimensional (2D) materials, such as MXenes, into the coating. The “labyrinth effect” created by the lamellar 2D structure of MXenes forms a longer and more tortuous diffusion path, effectively blocking the longitudinal penetration of corrosive ions and enhancing the barrier performance of the coating. To further enhance the corrosion protection provided by MXene fillers in the coating matrix, modification treatments are necessary to improve the dispersion of the MXene fillers and the overall quality of the coating. These modifications can effectively reduce the diffusion paths of aggressive ions. Additionally, the high specific surface area of MXenes allows them to store corrosion inhibitors, enabling the slow release of these inhibitors for long-term corrosion protection. This review summarizes the application of MXene in anti-corrosive coatings, including physical barrier and active protection. We begin by discussing the preparation of single or few-layer 2D MXene fillers. Next, we examine the use of pristine or modified MXenes as passivation fillers to strengthen coating integrity. Furthermore, we explore the use of MXenes as supports for corrosion inhibitors to endow the anti-corrosive coatings with active protection capabilities. Finally, the future development directions for MXene fillers are prospected, and the challenges of enhancing the corrosion protection of organic coatings were discussed.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109225"},"PeriodicalIF":6.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a series of ketocoumarin-based PIs (KCs) were designed and synthesized with various substituents, including methyl, trifluoromethyl, hydroxyl, phenyl, <em>p-</em>methylaminophenyl, and <em>p-</em>methylthiophenyl, linked to carbonyl. The primary objective was to explore the structure-reactivity-efficiency relationships of KCs, which are crucial for LED photopolymerization. The introduction of electron-withdrawing groups linked to carbonyl resulted in a relative redshift in absorption and enhanced photoinitiation efficiency in KCs. In contrast, the incorporation of electron-donating groups led to a blueshift in absorption or significant changes due to alterations in the chromophore's functional structure. These effects were confirmed through theoretical calculations. Notably, S-KC-F, with carbonyl connected to trifluoromethyl, exhibited superior photoinitiation performance, surpassing that of commercial PIs KC-01 and ITX under UV-LED irradiation. Additionally, S-KC-F exhibited good solubility, suggesting its potential for practical applications; however, its poor cytocompatibility may restrict its use in food packaging and biomedicine.
