Abstract: Disclosed is a method for making an antimicrobial material from 1D nanometer silver that does not accumulate in a human body. At first, 1D nanometer silver is mixed in hydrophilic solution to produce 1D nanometer silver solution. Then, adhesive is blended in the 1D nanometer silver solution to produce the antimicrobial material. The antimicrobial material may be used in antimicrobial liquid, antimicrobial dressing or antimicrobial composite. Human skin can easily block the 1D nanometer silver. Therefore, the 1D nanometer silver does not enter or accumulate in the human body. Yet, the antimicrobial material exhibits a high bactericidal rate.

Abstract: The invention discloses a method for continuously fabricating silver nanowires. The method mixes a glycol solution of a silver salt and a glycol solution of a polyvinyl pyrrolidone, and the mixed solution reacts in a temperature range and a time range to form the silver nanowires. The polyvinyl pyrrolidone has high boiling point and reduction ability so as to reduce the silver salt to the silver nanoparticles, and simultaneously, the polyvinyl pyrrolidone can provide barriers for limiting the particle growth. Besides, the oxygen functional groups on the long chains of the polyvinyl pyrrolidone can keep the stably one-dimensional growth of the silver nanoparticles to form the silver nanowires during the aging process.
