【 摘 要 】

In the present work, regenerated cellulose films with different pore sizes were prepared using cellulose, which can control the synthesis reaction of nano-ZnO and thus regulate its morphology. The results show that with 0, 4, and 8 g of cellulose applied, average pore sizes of samples increased from 7.0 nm to 14.4 and 20.1 nm, respectively. When no cellulose was used, only large Zn 5 (OH) 8 Cl 2 ·H 2 O (ZHC) flakes were prepared. Long ZnO nano-sheets and ZHC flakes with a mass fraction of 0.51 and 0.33, respectively, were prepared by adding 4 g cellulose; and ZnO nano-sheets with a mass fraction of 0.73, with 0.04 ZHC, were synthesised while using 8 g cellulose. The results reveal that the addition of cellulose can improve the average pore diameter of films and enhance the reaction rate of ZnO, resulting in the formation of ZnO nano-sheets/regenerated cellulose films.
