Abstract

There is provided a method for preparing a natural cellulose-AgO matrix having antimicrobial activity without leaching silver from the cellulose-AgO matrix. The method comprises: introducing silver ions (Ag+) into a natural cellulose matrix by dipping the natural cellulose matrix in an AgCl-dissolved NH4OH solution; and substituting hydrogen (H) of hydroxyl group (-OH) in natural cellulose with Ag+ by drying the silver ion-infused natural cellulose matrix, thus to form a natural cotton-AgO complex. The cellulose-AgO matrix prepared in the method may be useful to continuously maintain antimicrobial activity by maintaining an effective concentration of silver, which does not have cytotoxicity to human skin, and chemically bonded silver is not leached during the rehydration due to the chemical bond between the silver and the cellulose matrix.
