N,O-羧甲基壳聚糖抗菌染料的制备研究
Preparation of an antibacterial N, O-carboxymethyl chitosan dye
摘要
Abstract
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 measured using a color measuring instrument. The antibacterial property of N,O-carboxymethyl chitosan dye treated veneers was specific evaluated by colony counting method. The results showed that: numerous —OH and little —NH2 were replaced by—CH2 COOH, and —SO3- of the dye had a chemical reaction with protonated —NH3+ of N, O-carboxymethyl chitosan. The crystallinity of CTS was obviously decreased while the water solubility of N, O-carboxymethyl chitosan dye was notably improved. N, O-carboxymethyl chitosan dye obviously improved the dyeing effects and light fastness as well as water fastness were both enhanced. Additionally, the antibacterial properties of N, O-carboxymethyl chitosan dye were superior to reactive brilliant blue KN-R.关键词
