METHOD FOR MANUFACTURING SILVER NANOWIRES USING IONIC LIQUID

WIPO Patent Application WO/2014/092220

A1

The present invention relates to manufacturing silver nanowires having a diameter less than 100 nanometers and a length of 10 microns or more, and more particularly, to a method for uniformly manufacturing silver nanowires having a high aspect ratio using an ionic liquid as an additive in addition to components of silver salt precursors, reduction solvents, and capping agents in a method for synthesis of polyol using the silver salt precursors, the reduction solvents, and the capping agents. The feature of the present invention enables uniform formation of silver nanowires having a diameter less than 100 nanometers and a length of 10 microns or more. When the silver nanowires are dispersed in the solvents so as to form a film on a base film to thus form a transparent electrode film, the transparent electrode film may exhibit surface resistivity of 101-103Ω/□ range and light transmittance of 90% or more as compared with the light transmittance of the base film.
