NOVELTY - The method involves passing two dimensional (2D) material in compressible fluid through convergent-divergent nozzle to exfoliate 2D material before 2D material intercalates. The concentration of the 2D material in the compressible fluid is provided about 0.01 milligram per milliliter (mg/mL) to about 0.4 mg/mL. The convergent-divergent nozzle is provided with a de Laval nozzle, a valve, an orifice and a thin tube. The valve is provided with a needle valve, a butterfly valve, a globe valve, a pinch valve, an adjustable flow valve and a one-way flow valve. The 2D material in the compressible fluid is passed through the converging diverging nozzle at a pressure of about 200 pounds per square inch (psi) to about 4000 psi. The 2D material in the compressible fluid enters the convergent-divergent nozzle at a velocity less than the speed of sound in the compressible fluid. USE - Method for providing continuous production of exfoliated two-dimensional (2D) material. ADVANTAGE - The method is provided with reduced occurrence of defects and the versatility to be applied to any 2D layered material using any gaseous medium. The method isolates the exfoliation and suspension stabilization processes from each other environmentally friendly processing and reduced occurrence of defects that might otherwise arise in comparable ultrasound time-based treatment. The nanomaterial thickness, composition, and structural homogeneity are easy to control and the synthesized material is provided with high quality for producing highly sensitive electronic devices. The method is provided with high yields. The pressure is rapidly released to cause the gas molecules in between the layers to expand and separate the layers driven by the high pressure differential. The method increases the pressures and provides higher BN nanomaterial final concentrations indicating gradually improved yields in the process.
