Abstract
Described herein are methods for continuous production of an exfoliated two-dimensional (2D) material comprising passing a 2D material mixture through a convergent-divergent nozzle, the 2D material mixture comprising a 2D layered material and a compressible fluid. The method of the present disclosure employs physical compression and expansion of a flow of high-pressure gases, leaving the 2D layered material largely defect free to produce an exfoliated 2D layered in a simple, continuous, and environmentally friendly manner.
Claims23
A method for continuous production of an exfoliated two-dimensional (2D) material comprising
- a) providing a 2D layered material;
- b) providing a compressible fluid;
- c) mixing the 2D layered material with the compressible fluid thereby forming a 2D material mixture;
- and
- d) passing the 2D material mixture through a convergent-divergent nozzle to exfoliate the 2D layered material before the compressible fluid intercalates the 2D layered material.
A method for continuous production of exfoliated two-dimensional (2D) material comprising:
- a) providing a 2D layered material;
- b) providing a continuous flow of compressible fluid;
- c) feeding the 2D layered material into the continuous flow of compressible fluid thereby forming a continuous flow of a mixture of the 2D layered material and compressible fluid;
- and
- d) passing the continuous flow of the mixture of the 2D layered material and compressible fluid through a convergent-divergent nozzle to exfoliate the 2D layered material before the compressible fluid intercalates the 2D layered material.
