The thermal stability and photo-bactericidal effect of several tetra-cationic porphyrins and their zinc ion compounds immobilized onto cellulosic fabrics against S. aureus, P. aeruginosa, and E. coli were investigated and compared using a 100 W tungsten lamp. Immobilization of various concentrations of these photosensitizers onto cellulosic fabrics was carried out and characterized by ATR-FT-IR, DRS, TGA, and SEM. Applied cellulosic fabrics with the photosensitizers exhibited remarkable photo-stability, thermal stability, and antimicrobial activity against these studied strains.
研究并比较了几种固定在纤维素织物上的四阳离子卟啉及其锌离子化合物在100 W钨灯下对金黄色葡萄球菌、铜绿假单胞菌和大肠杆菌的热稳定性和光杀菌效果。将不同浓度的这些光敏剂固定在纤维素织物上，并通过衰减全反射傅里叶变换红外光谱（ATR-FT-IR）、漫反射光谱（DRS）、热重分析（TGA）和扫描电子显微镜（SEM）进行表征。含有光敏剂的纤维素织物对这些受试菌株表现出显著的光稳定性、热稳定性和抗菌活性。
