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. |
