Azo dye polymers were synthesized by an oxidative polycondensation reaction of naphthol based azo dyes with the oxidants NaOCl in an aqueous alkaline medium. These synthesized azo dye polymers were characterized by UV-Vis, FT-IR, 1H NMR techniques. The surface morphology of the azo dye polymers was understood by Scanning Electronic Microscopic study(SEM). The changes in weight in relation to change in temperature of synthesized compounds the was studied by TGA/DTA analysis. All the novel polymers were characterized to determine molecular weights by gel permeation chromatography(GPC). All of the azo dye monomers and polymers were researched for antibacterial (Corynebacterium xerosis, Bacillus brevis, Bacillus megaterium, Bacillus cereus, Mycobacterium smegmatis, Staphylococcus aureus, Micrococcus luteus Enterococcus faecalis, Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Yersinia enterocolitica) and antifungal (Kluyveromyces fragilis, Saccharomyces cerevisiae, Candida albicans) activities. When results of antibacterial activity of synthesized compounds was compared with standard Ampicillin, Streptomycin Sulfate, Nystatin. ıt is seen that the azo dye monomers had good antibacterial activity whereas the azo dye polymers did not have as good activity as the monomers. The dyes were examined in respect of their washing, water, sweat (acid and base) and frictional (dry and wet) fastness. From the results, It was found that The fastness properties of the azo dye monomers are better than the polymers. Because the bonding ability to the fabric in the monomers is better than the long chain polymers having a high molecular weight.

氧化缩聚反应合成基于萘酚的新型偶氮染料聚合物:抗菌活性和牢度研究

偶氮染料聚合物是通过萘酚基偶氮染料与氧化剂NaOCl在碱性水溶液中的氧化缩聚反应合成的。这些合成的偶氮染料聚合物通过UV-Vis,FT-IR,1 H NMR技术进行了表征。通过扫描电子显微镜研究(SEM)可以理解偶氮染料聚合物的表面形态。通过TGA / DTA分析研究了相对于合成化合物的温度变化的重量变化。通过凝胶渗透色谱法(GPC)对所有这些新型聚合物进行了表征,以测定分子量。研究了所有偶氮染料单体和聚合物的抗菌性(干燥杆菌,杆状芽孢杆菌,巨大芽孢杆菌蜡状芽孢杆菌,耻垢分枝杆菌,金黄色葡萄球菌藤黄微球菌粪肠球菌,鲍氏不动杆菌,铜绿假单胞菌肺炎克雷伯菌大肠埃希氏菌,小肠结肠炎耶尔森菌)和抗真菌剂(脆壁克鲁维酵母,酿酒酵母白色假丝酵母) 活动。当将合成化合物的抗菌活性结果与标准氨苄西林,硫酸链霉素,制霉菌素进行比较时。可以看出,偶氮染料单体具有良好的抗菌活性,而偶氮染料聚合物的活性不如单体。检查了染料的洗涤牢度,水,汗液(酸和碱)和摩擦牢度(干和湿)。从结果发现,偶氮染料单体的坚牢度性能优于聚合物。因为在单体中对织物的粘合能力比具有高分子量的长链聚合物更好。
