Introduction:
Ultrasonic graphene dispersion equipment
Graphene is the thinnest and hardest two-dimensional material in
the world composed of a single layer of carbon atoms. Its very good
strength, flexibility, electrical conductivity, and thermal
conductivity have important functions in various fields. In the
natural state, there is no single-layered inkene material-it
generally exists as three-dimensional graphite. It is very
important to extract single-layered graphene from graphite.
Ultrasonic graphene dispersion is also called ultrasonic graphene
peeling. The graphite oxide reduction method is used in conjunction
with ultrasonic vibration to effectively increase the distance
between graphite oxide layers. Graphite oxide with a large layer
distance is not only beneficial for other molecules and atoms to
insert between layers to form graphite oxide. Intercalation
composite materials can be easily peeled into single-layer graphite
oxide, laying a foundation for the further preparation of
single-layer graphene.
Ultrasonic dispersion principle
The ultrasonic nano-dispersion system / ultrasonic graphene
dispersion equipment uses the cavitation of ultrasonic waves to
disperse agglomerated particles. It is the
The granular suspension (liquid) is placed in a super-strong sound
field and processed with appropriate ultrasonic amplitude. In
cavitation effect, high temperature, high pressure, microjet,
strong vibration, etc.
Under the additional effect, the distance between the molecules
will continue to increase, eventually causing the molecules to
break up and form a single molecular structure. This product is
especially useful for dispersing nanomaterials
(Such as carbon nanotubes, graphene, silica, etc.) have good
results.
There are a large number of graphite materials in nature, and 1
millimeter thick graphite contains approximately 3 million layers
of graphene. Single layer of graphite is called graphene, in a free
state
This substance does not exist below, and all exist in the form of
graphite sheets laminated with multilayer graphene. Because the
interlayer force of the graphite sheet is weak, it can be carried
out by external force.
The layers were peeled off to obtain a single-layer graphene with a
thickness of only one carbon atom.
The ultrasonic graphene dispersion system uses the
ultrasonic-assisted Hummers method to prepare graphene oxide. It
uses a liquid as a medium and adds high-frequency ultrasonic
vibration to the liquid. Since ultrasound is a mechanical wave, it
is not absorbed by the molecules, and the vibrational motion of the
molecules is arched during the propagation process. Under the
effect of cavitation, that is, high temperature, high pressure,
microjet, strong vibration and other additional effects, the
distance between molecules increases its average distance due to
vibration, and eventually causes the molecules to break. The
distance between graphite oxide layers can be increased more
effectively, and with the increase of the ultrasonic power, the
interval between the obtained graphite oxide layers is increasing.
The pressure released by the instantaneous ultrasonic wave destroys
the van der Waals force between the graphene layer and the layer,
making it more difficult for graphene to cluster together. Graphite
oxide with a large interlayer distance is not only conducive to the
insertion of other molecules, atoms and other interlayers to form a
graphite oxide intercalation composite material, but also is easily
peeled into a single layer of graphite oxide
Lay the foundation for the further preparation of single-layer
graphene.
Ultrasonic dispersing equipment can be used for the dispersion and
homogenization of graphene, ink coatings, etc .; petroleum
emulsification; traditional Chinese medicine extraction processing;
cell, ballast water crushing, disinfection; accelerated reaction of
chemical raw materials.
