SILVER NANOWIRES, METHOD FOR PRODUCING SAME, AND SILVER NANOWIRE INK

摘要

Silver nanowires that are capable of significantly improving conductivity and visibility characteristics of a transparent conductor have attached to a surface thereof an organic protective agent, have an average diameter of 50 nm or less, an average length of 10 μm or more, and the organic protective agent is 1.5 to 8.0% by mass based on the total amount of the organic protective agent and silver. The silver nanowires can be made by circulating silver nanowires with the attached organic protective agent in a circulation flow channel having in a middle thereof a crossflow filter, along with a liquid medium. Crossflow filtration is performed with the filter while replenishing the liquid medium to the circulation flow channel continuously or intermittently, so as to wash off/remove a part of the organic protective agent on the surface of the silver nanowires to control an amount of the organic protective agent attached.
