^{Product Overview}

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

Graphene is a two-dimensional carbon element, and single-layer graphene is composed of a single layer of carbon atoms. Each carbon atom is connected in a sp ² hybridization 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 materials known, with excellent mechanical, electrical, and optical properties. It has low resistivity and superior conductivity, and the quantum Hall effect can be observed at room temperature. In addition, graphene also has 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 ¡ãC Graphene can also be connected to oxygen-containing groups to generate oxidized graphene, or connected to other groups to generate corresponding derivatives.

Graphene can be synthesized through methods such as mechanical exfoliation, chemical vapor deposition, oxidation-reduction, and electrochemistry.
