Anticorrosion performance of hydrophobic acid-modified-MOFs/epoxy coatings

Hydrophobic Porphyrin Titanium-Based MOFs for Visible-Light-Driven CO2 Reduction to Formate

“…However, the overfast crystallization process of titanium-based metals and carboxylic acid ligands limited the expansion of porphyrin titanium-based MOFs and their applications in the field of photocatalytic CO 2 reduction. − In the actual catalytic process, porphyrin titanium-based MOF materials lack long-term stability in a humid environment because of the easily hydrolyzed nature of Ti-based metal units. Accordingly, it is necessary to enhance the long-term stability of porphyrin titanium-based MOFs in humid environments through modification. − There are many strategies including bridging ligands, predesign of metal clusters, and postsynthetic modification to modulate the hydrophilicity and hydrophobicity of MOFs. , Among them, postsynthetic modification is the most commonly used strategy where without changing the intrinsic structure of the frameworks, MOFs can be modified with hydrophobic alkyl chains to enhance their stability under humid environments. − …”

pH-Responsive Fluorescent Metal–Organic Framework as a Functional Nanofiller for Smart Coatings

“…Metal–organic frameworks (MOFs), composed of metal ions connected by organic linkers, have received considerable attention in various fields owing to their large specific surface areas, rich active sites, designable frameworks, and great chemical stability. − MOFs can be used as nanofillers to improve the anticorrosion performance of the coatings. − Alipanah et al synthesized MIL-88A­(Fe) particles as corrosion-inhibiting fillers to enhance the protective property of the epoxy/polyamide coating . On the other hand, MOFs are attempted to be nanocontainers to load corrosion inhibitors for the self-repairing coatings. − Li et al selected a ZIF-8 nanocontainer with 2-mercaptobenzimidazole loading to prepare the self-repairing epoxy coating .…”
