一种细菌纤维素/姜黄素复合材料的制备及表征

Preparation and characterization of bacterial cellulose/curcumin composites

采用原位吸附法,将细菌纤维素(Bacterial Cellulose,BC)浸渍在不同浓度的姜黄素乙醇溶液中,经超声震荡,使BC对姜黄素吸附饱和,获得不同浓度下的BC/姜黄素复合材料。采用SEM、FTIR、XRD及水接触角测量仪等对BC/姜黄素复合材料性能进行测试表征。测试结果表明,原位吸附法成功地将姜黄素固定在BC材料中,随着姜黄素乙醇溶液浓度的提高,BC中吸附姜黄素的量增加,同时将试样置于潮湿环境下,吸附姜黄素的试样具有抗霉变特性,是一种具有应用前景的包装材料或组织工程材料。

Using in situ adsorption method, the bacterial cellulose （BC） was soaked to curcumin in ethanol soluti- onin. Curcumin was adsorbed into BC to obtained BC/curcumin composite materials with different concentrations. SEM, FTIR, XRD and contact angle measurement instrument were used to test the characterization and perform- ance of BC/cureumin composites. The results show that the curcumin could be introduced into BC materials by in si- tu adsorption method. As the concentration of curcumin increases, the amount of curcumin in the BC increases. The BC/curcumin composite samples in damp environment could prevent mildew. The BC/cureumin composites have good application prospect in packaging materials or tissue engineering materials.
