Abstract:
(EN) [Problem] To produce wires having a particularly large average length and a large average aspect ratio when synthesizing fine silver nanowires by an alcohol solvent reduction method. [Solution] A silver nanowire production method comprising a step in which silver is reductively precipitated into the form of a wire in an alcohol solvent in which a silver compound and an organic protective agent have been dissolved, said method being characterized in that a polymer having a vinyl pyrrolidone structural unit is used as the organic protective agent and the reductive precipitation is performed in a solution obtained by dissolving methyl-t-butyl ether in the alcohol solvent at a concentration of 0.3-25.0 mmol/L.
(FR) Le problème décrit par la présente invention est de fournir des fils présentant une longueur moyenne particulièrement importante et un rapport d'aspect moyen important, lors de la synthèse de nanofils d'argent fins par un procédé de réduction de solvant d'alcool. La solution selon l'invention porte sur un procédé de fabrication d'un nanofil d'argent consistant en une étape dans laquelle l'argent est précipité par réduction sous la forme d'un fil dans un solvant d'alcool dans lequel un composé d'argent et un agent de protection organique ont été dissous, ledit procédé étant caractérisé en ce qu'un polymère présentant une unité structurale de vinylpyrrolidone est utilisé en tant qu'agent protecteur organique et la précipitation réductrice est réalisée dans une solution obtenue par dissolution de méthyl-t-butyl éther dans le solvant d'alcool à une concentration de 0,3 à 25,0 mmol/l
(JA) 【課題】アルコール溶媒還元法で細い銀ナノワイヤを合成する際に、特に平均長さが長く、平均アスペクトの大きいワイヤを安定して生成させる。 【解決手段】銀化合物、有機保護剤が溶解しているアルコール溶媒中で、銀をワイヤ状に還元析出させる工程を有する銀ナノワイヤの製造法において、 前記有機保護剤としてビニルピロリドン構造単位を持つポリマーを使用すること、 前記アルコール溶媒中にメチル-t-ブチルエーテルが0.3~25.0mmol/Lの濃度で溶解している状態とし、その液中で前記還元析出を進行させること、 を特徴とする銀ナノワイヤの製造法。
