Conductive thin coating made of AgNWs

Preparation of AgNWs solutions

The wet slurry AgNWs in diameter <100nm, length >30nm purchased from Taobao supplier was mixed in IPA solution to a concentration of 0.066 mg mL−1 and sonicated for a further 30 min before use. The dispersion of AgNWs was then spin-coated (500 rpm for 20 s) onto the glass and heated on a hot plate at 60 °C for 5 min to remove any remaining organic solvent.
