Zinc oxide (ZnO) is a potential pigment material for paper coating to 
impart brightness and better printing properties. Nano–ZnO, due to its 
extremely small size, gives paper coating pigment a high covering power. 
In this work, zinc oxide -soluble starch nano composites was prepared by 
a simple method using zinc acetate and oxalic acid and soluble starch as 
stabilizing agent. The properties of paper before and after coating with 
nano zinc oxide were studied. The brightness and tensile of nano zinc 
oxide coated paper showed significant improvement than that of bulk –
ZnO coated paper. In addition, the nano-ZnO coated paper showed 
excellent anti-fungal and luminescence properties and resistance to absorb 
paraffin oil than that the paper treated by bulk ZnO that are much essential 
to enhance the life of paper.
