Salient Technical Feature including Competing Feature |
A simple process consisting of dip coating followed by heating in inert atmosphere is available for the production of graphene coated steel. The same process can also be extended for graphene coating over other substrate like quartz. The graphene coated substrates produced using this process have the following silent features: Improves the anti-corrosion properties of bare steel Quartz shows sheet electrical resistance of 1OkQ with transparency > 83%, can be used as a transparent conductor |
