Abstract

With the increasing global emphasis on public health, personal hygiene, and environmental safety, the development of effective strategies to inhibit microbial growth and transmission has become a critical research focus, driving rapidly expanding demand for antibacterial materials across multiple fields. UV-photocured antibacterial coatings have gained widespread adoption due to their fast curing rates, low energy consumption, and environmentally friendly characteristics. However, commercially available water-soluble photoinitiators such as Irgacure 2959, while exhibiting certain photosensitivity and low cytotoxicity, demonstrate poor compatibility with visible LED light sources. Herein, we present a novel class of visible LED-sensitive coumarin-ketone-pyridinium salt photoinitiators with varied anions, systematically investigating their photoinitiation performance and antibacterial properties. Our findings reveal that these dual-functional photoinitiators in combination with coinitiator N-phenylglycine (NPG) enable efficient and rapid photocuring when exposed to visible LED irradiation, with the water-borne coatings demonstrating excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. Notably, both the photoinitiators and resultant coatings exhibit good hemocompatibility, underscoring their promising potential for antibacterial coating applications.

期刊介绍： European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas: Polymer synthesis and functionalization • Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers. Stimuli-responsive polymers • Including shape memory and self-healing polymers. Supramolecular polymers and self-assembly • Molecular recognition and higher order polymer structures. Renewable and sustainable polymers • Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites. Polymers at interfaces and surfaces • Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications. Biomedical applications and nanomedicine • Polymers for regenerative medicine, drug delivery molecular release and gene therapy The scope of European Polymer Journal no longer includes Polymer Physics.
