Abstract:
(EN) [Problem] To stably produce particularly thin wires in cases where silver nanowires are synthesized by means of an alcohol solvent-based reduction method. [Solution] A method for producing silver nanowires, which comprises a step wherein silver is reduced and precipitated in the form of wires in an alcohol solvent in which a silver compound and an organic protection agent are dissolved. This method for producing silver nanowires is configured such that: a powder which is mainly composed of a polymer having a vinyl pyrrolidone structural unit and contains an acetic acid ester in an amount of from 0.002 to 0.040 mole relative to 1 mole of the polymer is used as a supply source of the organic protection agent; and the silver nanowires have an average diameter DM of 30 nm or less.
(FR) Le problème décrit par la présente invention est de produire de manière stable des fils particulièrement fins lors de la fabrication de nanofils d'argent par un procédé de réduction utilisant un solvant alcoolique. À cet effet, l'invention concerne un procédé de production de nanofils d'argent qui comprend une étape au cours de laquelle de l'argent est réduit et précipité sous la forme de fils dans un solvant alcoolique, dans lequel sont dissous un composé d'argent et un agent de protection organique. Ce procédé de production de nanofils d'argent est configuré de telle sorte qu'une poudre, qui est principalement composée d'un polymère ayant un motif structural vinylyrrolidone et contient un ester d'acide acétique en une quantité de 0,002 à 0,040 mole pour 1 mole du polymère, est utilisée comme source d'alimentation en agent de protection organique ; et les nanofils d'argent ont un diamètre moyen DM de 30 nm ou moins.
(JA) 【課題】アルコール溶媒還元法で銀ナノワイヤを合成する際に、特に細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、前記有機保護剤の供給源として、ビニルピロリドン構造単位を持つポリマーを主成分とし、前記ポリマー1モルに対し酢酸エステルを0.002~0.040モルの割合で含有する粉体を用いる、平均直径Dが30nm以下である銀ナノワイヤの製造法。
