Ultrasonic Graphene Dispersion System

Since the special properties of graphite are known, several methods of graphite preparation have been developed. Graphene is prepared from graphene oxide through a complex chemical process, during which very strong oxidizing and reducing agents are added, and graphene prepared under these harsh chemical conditions often contains a large number of defects.

Ultrasonic is a proven alternative that can produce large quantities of high-quality graphene. Graphite is added to a mixture of dilute organic acids, alcohols, and water, and the mixture is then exposed to ultrasonic radiation. The acid acts as a “molecular wedge” that separates the graphene sheets from the parent graphite. Through this simple process, a large amount of undispersed, high-quality graphene dispersed in water was produced.

 

 

Graphene is a two-dimensional carbon nanomaterial in which carbon atoms form a hexagonal honeycomb lattice with sp² hybrid orbitals. Graphene’s carbon-atom-thick sheets of carbon form graphite through non-bonding interactions and have an extremely large surface area.

“It is the thinnest substance in the universe and the strongest substance ever created. It exhibits enormous intrinsic carrier mobility, has the smallest effective mass (zero), and can perform micrometer-long distances at room temperature.” Spread without scattering. Graphene can sustain current densities six orders of magnitude higher than copper, exhibits record thermal conductivity and hardness, is airtight, and can reconcile conflicting properties such as brittleness and ductility. Electronics in graphene The transport is described by the Dirac equation, which allows the study of relativistic quantum phenomena in benchtop experiments.

Principle of Ultrasonic Graphene Dispersion
Ultrasonic graphene dispersion equipment uses ultrasonic cavitation to disperse agglomerated particles. It puts the particle suspension (liquid state) to be treated into a super-strong sound field and treats it with an appropriate ultrasonic amplitude. Under the cavitation effect, high temperature, high pressure, micro-jet, strong vibration and other additional effects, the distance between molecules will continue to increase, which will eventually lead to molecular fragmentation and the formation of a single molecular structure. This product is especially effective for dispersing nanomaterials (such as carbon nanotubes, graphene, silicon dioxide, etc.).

Graphene Dispersion Purpose
There are a large number of graphite materials in nature, and graphite with a thickness of 1 mm contains about 3 million layers of graphene. Single-layer graphite is called graphene, which does not exist in a free state, but exists in the form of graphite sheets stacked with multi-layer graphene. Due to the weak interlayer force of graphite sheets, the layers can be peeled off by external force, so as to obtain single-layer graphene with a thickness of only one carbon atom.
