N,O-羧甲基壳聚糖抗菌染料的制备研究OA北大核心CSCDCSTPCD
Preparation of an antibacterial N, O-carboxymethyl chitosan dye
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—CH2 COOH基团取代,染料中的—SO3…查看全部>>
Chitosan and reactive brilliant blue KN-R were used to prepare a novel N,O-carboxymethyl chitosan dye by a two-step reaction. FTIR, XRD and elemental analyzer were employed to explore the chemical groups and structure of the obtained new dye. Besides, the water solubility was tested using a UV-visible spectrophotometer. The color parameters and color fastness of N, O-carboxymethyl chitosan dye dyed veneers with impregnating in atmospheric pressure were measu…查看全部>>
