Special Issue Information

Dear Colleagues,

Organic coatings are protective or functional overlays created through the deposition of organic polymer substances, such as resins and polymers, onto substrate materials including metals, plastics, and timber. Comprising a resin matrix, pigments, solvents, and additives, they establish an impermeable shield that safeguards substrates from moisture, atmospheric oxygen, corrosive chemicals, and UV radiation, thereby prolonging material durability and curtailing maintenance expenditure. Within industrial contexts, these coatings prove indispensable for anti-corrosion measures (e.g., pipelines, marine vessels), enhancing vehicular corrosion resistance and improving the weatherproofing of architectural facades. Domestically, they serve dual decorative and protective purposes in appliances and domestic furnishings. Cutting-edge coating innovations now integrate specialised capabilities, such as electrical conductivity, antimicrobial action, and self-repair mechanisms. As an economical, adaptable surface treatment, organic coatings hold unparalleled significance in augmenting material performance, conserving resources, and advancing sustainable practices.

In this case, this Special Issue aims to compile original and cutting-edge research work in the development, characterization, and application of organic coatings.

The oxygen inhibition and migration of micromolecules which stem from photoinitiators (PIs) remain two critical challenges to address in radical photocuring. In this work, we reported a one-step ternary copolymerization strategy to construct a one-component macromolecular photoinitiator (PPI) using polymerizable thioxanthone (TX), amine (N), and fluorinated alkane (F) as monomers. Then, we utilize the low surface energy of F unit and macromolecular skeleton to reduce oxygen inhibition and migration. Compared to micromolecule TX, PPI also exhibits a broad absorption in the 250–430 nm range, and a higher molar extinction coefficient. The effects of the TX, N, and F component ratios on the photoinitiation efficiency of PPI were systematically investigated, and the photopolymerization kinetics revealed that the increased content of F unit can eliminate the oxygen inhibition of PPI. As a result, PPI demonstrates the more superior photoinitiation efficiency compared to the traditional TX/N two-component macromolecule photoinitiation system. Migration experiments indicated that there is a 60% reduction in the migration rate for PPI compared to the TX/N photoinitiation system. This work provides an effective strategy to address oxygen inhibition and micromolecule migration issues in radical photocuring, showing potential applications in food and pharmaceutical packaging fields.
