Product Name

Name: Single Layer Graphene dispersion water(XFZ20)

Product Overview

Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms in a hexagonal honeycomb lattice, with numerous unique properties, widely used in various fields. The research on graphene can be traced back to 1948, when Austrian scientists Russ and Wager were the first to use transmission electron microscopy to capture images of a small amount of graphene layers. In 2004, British scientists Andrei Geim and Konstantin Novoselov successfully peeled off a single layer of graphene, which attracted widespread attention and won them the 2010 Nobel Prize in Physics.

Graphene is a two-dimensional carbon element, and single-layer graphene is composed of single-layer carbon atoms. Each carbon atom is connected in sp ² hybrid form to form a hexagonal honeycomb like two-dimensional structure. The C-C bond length in graphene is about 0.142nm, the bond angle is 120 °, and the thickness is only 0.35nm.

Graphene is currently one of the strongest known materials, with excellent mechanical, electrical, and optical properties. It has a low resistivity and superior conductivity, and the quantum Hall effect can be observed at room temperature. In addition, graphene also possesses transparency and nonlinear optical properties.

The reactivity of graphene is mainly concentrated at the boundary groups and planar defects. It can be oxidized at high temperatures or react with oxidizing acids to produce products such as CO and CO â‚? Graphene can also be connected to oxygen-containing groups to generate graphene oxide, or connected to other groups to generate corresponding derivatives.

Product Features

The graphene provided by Xianfeng Nano is prepared by ultrasonically adding dispersant XFZ20 to rGO in a solvent:
High single-layer rate: Composed of single atomic layers, it reduces the resistance caused by interlayer van der Waals forces, resulting in more excellent performance.
High purity: The content of dispersant added is low, which has a relatively small impact on the performance of graphene.
Rich functional groups: rGO has various functional groups on its surface, such as carboxyl, hydroxyl, epoxy, etc., which makes it easy to react with organic compounds.
Large specific surface area: During the preparation process, a larger specific surface area is generated, which is beneficial for interacting with other substances.
Excellent conductivity and thermal conductivity: Due to its excellent conductivity, rGO has potential applications in energy storage, composite materials, sensors, and other fields.
