Preparation method of water-based silver nanowire ink

[0022] Examples:

[0023] Use silver nanowires with a diameter of 30-50nm and a length of 10-20μm as the conductive material. Select sodium carboxymethyl cellulose as the binder, Zonyl FSO-100 as the surfactant, Spredox D-260 as the dispersing anti-settling agent, propylene glycol methyl ether as the leveling agent, 2-hexyl ethanol as the defoaming agent, and water as the solvent. Prepare slurry;

[0024] The sodium carboxymethyl cellulose is formulated into a 1.5% aqueous solution (note: a larger concentration will cause the viscosity to be too large to be taken out). Then determine the content of these components, calculate the required quality of each additive. Add the rest of the materials except the sodium carboxymethyl cellulose solution to the flask, stir and mix for 20 minutes. Then slowly drip the sodium carboxymethyl cellulose solution into the slurry and continue to stir for 30 minutes. Finally, the slurry was filtered with a 20 μm pore size filter membrane to obtain the final ink.
