Abstract

Polymer materials are widely used in medical materials, food packaging, coatings, and other fields. However, the surface of the materials is easily contaminated by microorganisms, resulting in serious problems. To solve this issue, a new type of antibacterial polymer fluorescent coating was successfully synthesized by copolymerization of divinylbenzene with 7-methacryloxy-4-methyl coumarin, dodecafluoroheptyl methacrylate, and other monomers. The surface structure and thermal stability of the coating were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis. Fluorine was polymerized into the polymer, improving the thermal stability compared to polystyrene and polydivinylbenzene. The bactericidal and antibacterial adhesion properties of the coating materials were studied by a contact germicidal test and antibacterial adhesion test. The polymer had a strong inhibitory effect on Staphylococcus aureus. After immersion in room temperature water, the film maintained its strong inhibitory effect on S. aureus fluorescence intensity and had high fluorescence stability.

香豆素类抗菌聚合物荧光涂料的合成与表征

高分子材料广泛应用于医疗材料、食品包装、涂料等领域。然而，材料的表面很容易被微生物污染，导致严重的问题。为了解决这一问题，以二乙烯基苯与7-甲基丙烯酰氧基-4-甲基香豆素、甲基丙烯酸十二氟庚酯等单体共聚，成功合成了一种新型抗菌聚合物荧光涂料。通过傅立叶变换红外光谱、扫描电子显微镜和热重分析对涂层的表面结构和热稳定性进行了表征。氟被聚合到聚合物中，与聚苯乙烯和聚二乙烯基苯相比，提高了热稳定性。通过接触杀菌试验和抗菌粘附试验研究了涂层材料的杀菌和抗菌粘附性能。该聚合物对金黄色葡萄球菌有很强的抑制作用。在室温水中浸泡后，该膜保持了对金黄色葡萄球菌荧光强度的强烈抑制作用，并具有较高的荧光稳定性。
