Abstract
In this study silver nano particles was used to improve the antibacterial properties of paper. This material was used at two levels of concentration (25 ppm and 100 ppm in pulp suspension). All hand-sheet’s antibacterial properties were evaluated using the OD method. In this method Escherichia coli bacteria and Bacillus subtilis bacteria were used that theses tow bacteria are representative of Gram-positive and Gram-negative bacteria respectively. Results have shown that nano silver particles at the same consumption levels had a larger reduction in growth of E. coli in comparison to Bacillus. Also, all concentration levels of nano silver reduced the growth of both bacteria, but low consumption value of nano silver (ppm 25) reduced the growth of both bacteria significantly that is very important in terms of its safety and health. Finally, according to the results, the use of nano silver didn’t show conventional negative effects of additives and fillers on reducing of some physical, mechanical and optical properties.
