ATOMICALLY THIN CRYSTALS AND FILMS AND PROCESS FOR MAKING SAME |
| 摘要 |
The invention provides a process for exfoliating a 3-dimensional layered material to produce a 2-dimensional material, said process comprising the steps of mixing the layered material in a solvent to provide a mixture; applying energy, for example ultrasound, to said mixture, and removing the energy applied to the mixture, such that sedimentation of the 2-dimensional material out of solution as a weakly re-aggregated, exfoliated 2-dimensional material is produced. The invention provides a fast, simple and high yielding process for separating 3-dimensional layered materials into individual 2-dimensional layers or flakes, which do not strongly re-aggregate, without utilising hazardous solvents. |

1. A process for exfoliating a 3-dimensional layered material to produce a 2-dimensional material said process comprising the steps of:
mixing the layered material in water to provide a mixture; applying energy, for example ultrasound, to said mixture to exfoliate the 3-dimensional layered material and produce dispersed exfoliated 2-dimensional material; and removing the energy applied to the mixture, such that sedimentation of the 2-dimensional material out of solution as a weakly re-aggregated, exfoliated 2-dimensional material is produced. |
