The infectious diseases caused by various bacteria pose serious threat to human health. To solve this problem, antibacterial agents have been widely used in people’s daily life to deactivate or kill these bacteria. Among the antibacterial agents, ZnO is one of the most promising metal oxide antibacterial agents due to its non-toxic nature and safe properties. To expand its application, many composites of ZnO have been widely studied. Cellulose, as one of the most abundant biopolymers, has many merits like biodegradability, biocompatibility and low cost. Thus, many studies focus on synthesized cellulose/ZnO. The synthetic strategy includes both chemical and physical methods. Many of them have been shown that cellulose/ZnO composites have excellent antibacterial activity and are environment-friendly and have many applications for example food packing, antibacterial fibers and so on. This review mainly discusses the preparation methods of cellulose/ZnO and their effect on the morphology and properties.

Abstract. series of ZnO nanomaterials were synthesized by assistant of sodium lignosulphonate (SLS) using hydrothermal method. And nanoplates, nanoflowers structures of ZnO have been fabricated successfully. XRD、SEM and PL were applied to characterize the prepared ZnO. XRD analysis indicated that prepared ZnO had preferential growth along the c-axis. The effection of synthesis conditions on ZnO crystal growth were studied by SEM. And the result showed that the concentration of Zn 2+ and SLS play an important role on the formation of morphology of ZnO. The results of photolumiscience studies show that hierarchical nanoflowers-like ZnO prepared with SLS has a weaker visible emission. This indicated that the presents of SLS can deduced the defects concentration during ZnO crystal growth.
