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.
