Preparation of an antibacterial N,O-carboxymethyl chitosan dye.

  • 摘要: 以壳聚糖(CTS)和活性艳蓝KN-R染料为原材料,通过两步反应法制备新型N,O-羧甲基壳聚糖染料,用红外光谱(FTIR)、X射线衍射(XRD)、元素分析仪分析其结构和化学基团,并用紫外可见分光光度计对其水溶性进行检测;采用常压浸渍法制备N,O-羧甲基壳聚糖染料染色薄木,用光谱光度仪进行表面颜色及日晒和水洗色差测量;用菌落计数法定量表征其抗菌性能。结果表明:CTS分子中大量—OH、少量—NH2基团被—CH2COOH基团取代,染料中的—SO-3和N,O-羧甲基壳聚糖中质子化的—NH+3发生反应;羧甲基化和染料接枝反应使得CTS结晶度下降;N,O-羧甲基壳聚糖染料的水溶性得到显著改善;N,O-羧甲基壳聚糖染料可明显改善薄木的染色效果,且染色薄木的耐日晒和耐水洗牢度均提高;N,O-羧甲基壳聚糖染料染色薄木的抗菌性能优于活性艳蓝KN-R染色薄木。
