Silver-chromium alloy nanowire and preparation method therefor

Abstract

The invention discloses a silver-chromium alloy nanowire having a diameter of 18 to 60 nm, a length of 5 to 100 μm, wherein a molar ratio of the silver to chromium is 1:0.01-3. The preparation method of the silver-chromium alloy nanowire comprises the steps of: a. preparing a reaction solution: formulating a silver source, a chromium source, polyvinylpyrrolidone and a reductive agent into a reaction solution, or adding the materials into deionized water to formulate a reaction solution; and b. performing a reductive reaction: performing a reductive reaction by maintaining the reaction vessel at a temperature of 120° C. to 200° C. for 2-10 hours to obtain a silver-chromium alloy nanowire suspension. The minimum diameter of the silver-chromium alloy nanowire of the present invention may reach 18 nm and its length is usually 20 μm or above. Thus, it has a broad application prospect.
