中文摘要:

      纳米氧化锌（ZnO）具有的表面与界面效应、量子尺寸效应、体积效应和宏观量子隧道效应以及高透明度、高分散性等特点，使其在化学、光学、生物和电学等方面表现出许多独特优异的物理和化学性能而得到关注。纤维素作为自然界中含量最多、分布最广的天然高分子聚合物，其不仅来源非常丰富，而且无毒害、可再生、可生物降解，已成为当今研究的热点。纳米ZnO-纤维素复合材料充分发挥纳米ZnO和纤维素两者的优点被广泛应用于包装、医药、电化学等领域。本文介绍了制备纳米ZnO的几个重要方法，重点综述了纳米ZnO-纤维素复合材料的研究进展，对纳米ZnO-纤维素复合材料的研究方法及应用进行了展望。

Abstract:

      Nano-sized zinc oxide (ZnO) has fantastic properties in chemistry, optics, biology and electricity due to its surface and interfacial effects, quantum size effect, volume effect, macroscopic quantum tunnel effect, high transparency and high dispersity, which make it attract wide attention. Cellulose is the world’s most abundant natural polysaccharide. It has also become a hot research topic because of widely available, non-toxic, renewable and biodegradable. Nano-ZnO/cellulose composites give full play to the advantages of both nano-ZnO and cellulose. It will be widely used in packaging, medicine, electrochemistry and other fields. This review presented the main preparing methods of ZnO nanoparticles and research progress of nano-ZnO/cellulose composites. The future research emphasis and trends were also discussed.
