摘　　要：目的将来源于自然的细菌纤维素作为包装材料应用于包装领域,以取代传统的塑料包装材料。方法综述近几年细菌纤维素在包装领域的研究与应用现状,介绍细菌纤维素的基本培育过程、改性技术和制备方法,阐述细菌纤维素在包装领域的研究与应用。结果细菌纤维素通过层层组装、聚合、联接等方式,可与多种聚合物高效复合,形成不同微观尺寸和结构特性的纤维素基多孔复合材料,从而改善其力学性能和物理性能,并可调控其阻隔性能和抗菌灭菌性能。常用细菌纤维模式为纳米细菌纤维和纳米细菌晶须。结论细菌纤维素材料及其复合材料完全可以替代塑料用于包装领域,在食品包装和智能包装上的研究和应用前景较大。This thesis aims to explore the application of natural bacterial cellulose(BC) as packaging material in packaging field to replace traditional plastic packaging material. The research and application of BC in packaging field in recent years were reviewed;the basic cultivation process, modification technology and preparation method of BC were introduced;and the research and application of BC in packaging field were expounded. BC can be efficiently compounded with various polymers by means of layer-by-layer assembly, polymerization, connection, etc., to form cellulose-based porous composites with different microscopic sizes and structural characteristics, thereby improving its mechanical and physical properties, and regulating its barrier properties and antibacterial and sterilization properties. The common bacterial fiber modes are nanobacterial fiber and nanobacterial whisker. Bacterial cellulose materials and their composites can completely replace plastics, applying in the packaging industry, and have great research and application prospects in foodpackaging and intelligent packaging.
