Study on UV-cured antimicrobial coatings with epoxy resin quaternary ammonium salt
This study aims to develop light-cured antimicrobial coatings were developed by dispersing epoxy resin F51-Quaternary Ammonium Salts (F51-QAS) as antimicrobial agents in light-cured emulsions. The molecular structures of these F51-QAS were analyzed using infrared spectroscopy. Thermogravimetric analysis was performed to evaluate the thermal stability of the antimicrobial coatings. Contact angle testing was conducted to investigate the hygroscopic wettability of the coatings. Mechanical properties such as pencil hardness, adhesion strength, flexibility, and impact resistance were evaluated. Antimicrobial rate experiments were conducted to examine the antimicrobial properties of the coatings. The antimicrobial properties were examined through rate experiments against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Results showed that when the F51-QAS content was at 2.7%, the light-cured antimicrobial coatings exhibited excellent overall performance with 100% antimicrobial rate.

期刊介绍：
The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace.
Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
