摘要：
A novel simple gas-driven exfoliation method with mild operating conditions is explored for producing graphene. The obtained graphene, with 97% of flakes being <= 2 layers and 62% mono-layers, is of high-quality and free of defects. A high sheer rate of up to 3.3 x 10(7) s(-1) generated due to the driving of high-speed gas at a working pressure as low as 0.5 MPa is responsible for the exfoliation.
