银奈米线的制造方法与银奈米线以及使用该银奈米线的印墨;METHOD FOR PRODUCING NANO SILVER WIRE AND NANO SILVER WIRE, AND INK USING THE NANO SILVER WIRE

摘要

本发明之课题，系稳定地制造一种适合于制造透明导电体之细而长的银奈米线。本发明之解决手段，系提供一种银奈米线的制造方法，其系在溶解有银化合物之醇溶剂中使银还原析出成为线状之银奈米线的制造方法，其中：在溶解有氯化物、溴化物、硷金属氢氧化物、铝盐及有机保护剂之醇溶剂中进行前述析出；将溶解在前述溶剂之铝盐的Al总量与硷金属氢氧化物的氢氧化物离子总量之莫耳比Al/OH设为0.01至0.40；及将溶解在前述溶剂之硷金属氢氧化物的氢氧化物离子总量与银化合物的Ag总量之莫耳比OH/Ag设为0.005至0.50。;Provided is a method for producing a nano silver wire by reduction-precipitating a wire-like nano silver wire from a alcohol solvent with a silver compound dissolved therein, wherein the precipitating is conducted in an alcohol solvent with a chloride, a bromide, an alkali metal hydroxide, an aluminum salt and organic protecting agent dissolved therein; the molar ratio Al/OH of the total Al amount of the aluminum salt to the total amount of hydroxide ion of the alkali mental hydroxide which are dissolved in the solvent is 0.01 to 0.40; and the molar ratio OH/Ag of the total hydroxide ion amount of the alkali metal hydroxide to the total Ag amount of the silver compound which are dissolved in the solvent, is 0.005 to 0.50.
