We get the Steeping-Taking Graphene Film by coating a layer of organic polymer film on the surface of graphene and undergoing backside purification treatment.
After steeped in etching liquid to etch copper and rinsed with deionized water, it can be easily transferred. The organic polymer film can be moved by acetone.
- Grade B’s monolayer coverage is more than 85%.
- We can also provide customization services.
