The present invention relates to a method for manufacturing a chitosan-silver nanocomposite and an antibacterial paper coated with a chitosan-silver nanocomposite wherein the method for manufacturing chitosan-silver nanocomposite comprises a step of adding a silver nitrate solution in a chitosan solution, stirring and putting the same in an autoclave, and reacting the same. If a chitosan-silver nanocomposite is manufactured in accordance with the manufacturing method of the present invention, it is possible to reduce a production rate of Ag, to manufacture a chitosan-silver nanocomposite environment friendly, to reduce processing facilities, and to reduce energy required for manufacturing conducive to a very economic manufacturing as well as a mass production as advantages. In addition, the paper coated with the chitosan-silver nanocomposite or the chitosan-silver nano-film manufactured by the method of the present invention shows excellent antibacterial properties and therefore, may be effectively used as a packing paper of foods, agricultural products, medical equipment and pharmaceutical products.;COPYRIGHT KIPO 2015
