【摘要】：以纤维素为基体制备的功能复合材料,可赋予纤维素光、电、磁以及催化等性能,在制浆造纸、精细化工、组织工程、生物医药等领域具有广阔的应用前景。纤维素基生物医用复合材料是纤维素功能复合材料的典型代表,它结合了生物质材料和生物材料的优点,在骨修复替代、组织工程、药物缓释、基因载体以及蛋白质吸附等领域具有潜在的应用价值,是当前生物质领域的研究热点。综述了目前制备复合材料常用的3种方法,即水热(溶剂热)法、微波辅助法和超声波法,并对这几种方法的特点进行了分析;同时对纤维素功能复合材料发展现状进行了概述,系统介绍了纤维素/羟基磷灰石、纤维素/碳酸钙以及纤维素/银等生物医用复合材料的研究进展。最后,结合笔者自身的研究经历,探讨了纤维素基生物医用复合材料开发过程中存在的问题以及今后的发展方向。
[Abstract]:The functional composites prepared with cellulose as matrix can give cellulose light, electricity, magnetic and catalytic properties. It has a broad application prospect in pulp and paper making, fine chemical industry, tissue engineering, biomedicine and so on. Cellulose based biomedical composite is a typical representative of cellulose functional composites. It combines the advantages of biomaterials and biomaterials, in bone repair substitution, tissue engineering, drug delivery, Gene vector and protein adsorption have potential application value and are the research hotspot in biomass field. In this paper, three common methods for preparing composite materials, namely hydrothermal method, microwave assisted method and ultrasonic method, are reviewed, and the characteristics of these methods are analyzed. The research progress of cellulose / hydroxyapatite, cellulose / calcium carbonate and cellulose / silver biomedical composites were also reviewed. Finally, based on the author's own research experience, the problems in the development of cellulose based biomedical composites and the future development direction are discussed.
