Abstract :
Transparent and conductive coatings were achieved on glass by dissolving graphene oxide into dionized water followed by spray-coating on preheated substrate, chemical and thermal reduction. SEM shows the spray-coating graphene oxide coatings and the reduced graphene oxide coatings are uniform. No obvious aggregation was observed. UV-vis transmission spectra shows 65% transmittance at 550 nm of the graphene coatings with 15 kΩ/□.
