SILVER NANO WIRE AGGREGATE, SILVER NANO WIRE DISPERSION LIQUID, SILVER NANO WIRE INK, AND PRODUCTION METHOD THEREFOR

摘要

In the first aspect of the present invention, the silver nano wire aggregate has a mean diameter of between 10 nm and 35 nm inclusive, and a mean length of 9 μm or more. The difference between the maximum diameter and the minimum diameter of the silver nano wires in the aggregate is 19.5 nm or less. In the second aspect of the present invention, the silver nano wire aggregate has a mean diameter of between 10 nm and 35 nm inclusive, and a mean length of 9 μm or more. The difference between the cumulative 97% diameter and the cumulative 3% diameter of the silver nano wires in the aggregate is 13.0 nm or less. The silver nano wire dispersion liquid and the silver nano wire ink contain the silver nano wire aggregate dispersed in a liquid medium. The silver nano wire aggregate production method, the silver nano wire dispersion liquid production method, and the silver nano wire ink production method comprise reducing and precipitating into a wire shape the silver in an alcohol solvent wherein an organic protectant and a silver compound have been dissolved, performing the reduction and precipitation of the silver at a holding temperature of 95°C or lower, and performing filtration through a filter with a prescribed mesh size.
