摘要:
A method for producing a silver nanowire dispersion liquid which exhibits good separability among wires, including: subjecting a liquid having dispersed therein silver nanowires having an average length of 10 μm or more, to at least once of filtration including filtration with an organic fiber mesh filter having an aperture of 8 μm or more and 120 μm or less, so as to provide a filtrate having dispersed therein silver nanowires having an average length of 10 μm or more (preliminary filtering step); and subjecting the filtrate obtained in the preliminary filtering step, to at least once of filtration including filtration with an organic fiber mesh filter having an aperture of 12 μm or less, so as to provide a filtrate having dispersed therein silver nanowires having an average length of 10 μm or more (finish filtering step).
