Abstract
Provided are a method of isolating and purifying metal nanowires from a crude and complex reaction mixture that includes relatively high aspect ratio nanostructures as well as nanostructures of low aspect ratio shapes, and conductive films made of the purified nanostructures.
Claims7
A conductive film comprising:
- a conductive network of a plurality of silver nanowires that has a resistance of at least 200 ohm/sq;
- and
- no more than 1500 nanostructures having an aspect ratio of less than 10 per millimeter square area of the conductive film.
