Description
Technical Field
The invention relates to a method for stripping oxide nanosheets by ultrasonic.
Background
Two-dimensional nanomaterials have great application potential in various fields, such as condensed physical, material science, nanotechnology, and the like. Common two-dimensional materials include boron nitride, graphene, transition metal compounds, black phosphorus, and the like. Among them, two-dimensional oxide materials are widely used in the fields of printed electronics, flexible electronics, memories, processors, supercapacitors, sensors, solar cells, semiconductor manufacturing, and the like, due to their excellent electrical, thermal, and optical properties.
The wide use of two-dimensional materials is also increasingly in demand. The existing mature preparation methods comprise: micro-mechanical stripping, mechanical force assisted liquid stripping, ion intercalation assisted liquid stripping, ion exchange assisted liquid stripping, oxidation assisted liquid stripping, selective etch assisted liquid stripping, chemical vapor deposition, and the like. At present, in the preparation of two-dimensional oxide materials, more users use ion intercalation auxiliary liquid stripping, and the ion intercalation auxiliary liquid stripping is a typical two-dimensional material preparation method from top to bottom. The basic idea of this method is to insert salt-based ions with small ionic radius, such as lithium ions, sodium ions, potassium ions or copper ions, into the gaps of the layered crystal, and the insertion of the ions can effectively increase the gaps between adjacent layers and reduce the van der waals force between the layers. Under specific solvent treatment, the ionic intercalated mixture can be stripped into nano-sheets.
However, this method has limitations in that the peeling process takes a long time and the size of the nanosheets cannot be effectively controlled. With the wider application of the two-dimensional oxide material, the demand of each field is larger and larger, so that a method capable of improving the stripping yield and efficiency of the oxide nanosheet is urgently needed.
