一种细菌纤维素/姜黄素复合材料的制备及表征
|
Abstract:
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 solutionin. 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 performance of BC/curcumin composites. The results show that the curcumin could be introduced into BC materials by in situ 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/curcumin composites have good application prospect in packaging materials or tissue engineering materials. 国家自然科学基金（51403153）；天津市科技特派员项目（16JCTPJC49200）
