Abstract

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.

环氧树脂季铵盐紫外光固化抗菌涂料的研究

以环氧树脂f51 -季铵盐(F51-QAS)为分散剂，在光固化乳剂中制备光固化抗菌涂料。利用红外光谱分析了这些F51-QAS的分子结构。采用热重法评价抗菌涂层的热稳定性。通过接触角测试研究了涂层的吸湿性。机械性能，如铅笔硬度，粘接强度，柔韧性和抗冲击性进行了评估。通过抗菌率实验考察了涂层的抗菌性能。通过对大肠杆菌(E. coli)和金黄色葡萄球菌(S. aureus)的抑菌率实验考察了其抗菌性能。结果表明，当F51-QAS含量为2.7%时，光固化抗菌涂层整体性能优异，抗菌率为100%。

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.
