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.

Moderate viscosity makes it easy to compound into water-based coatings of different concentrations.

Application Fields

Automotive electrostatic spraying light colored primer: In the coating of automotive plastic parts, using graphene as a conductive agent can avoid the problem of darkening the color of the conductive primer and meet the color requirements of automotive electrostatic spraying.

Anti static coating: Graphene has good conductivity and corrosion resistance, and can be applied to occasions with high requirements for fire and explosion prevention, such as the inner and outer walls of oil storage and transportation equipment in industries such as petroleum, chemical, railway, and transportation, as well as anti-corrosion coatings for equipment in industries such as coal mining, aviation, textile, and grain.

Epoxy zinc rich paint: Adding graphene to existing epoxy anti-corrosion coatings can improve the coating's impact resistance, adhesion, water resistance, hardness, and other indicators. It is widely used in equipment anti-corrosion in fields such as marine engineering, transportation, large industrial equipment, and municipal engineering facilities.

Waterborne anti-corrosion coating: Adding graphene to water-based anti-corrosion coating can improve the surface tension of the coating, enhance the film-forming and anti-corrosion properties of the paint film.

Flame retardant coating: the anime structure of graphene monomer is dispersed into the paint film and stacked layer by layer to form a dense isolation layer, which can play the role of fire prevention and flame retardancy. After crosslinking with resin molecules, the isolation effect is further strengthened and the flame retardant effect is better. In addition, the products of graphene coating combustion, in addition to carbon dioxide and water, will also leave continuous carbon layers in place, thereby further improving the flame retardant effect.

High thermal conductivity and heat dissipation coating: Adding graphene to the coating can significantly improve its thermal conductivity, making it suitable for many harsh usage environments.

High strength coating: After adding graphene to the coating, it forms a network structure during the curing process of the paint film, enhancing the adhesion between the paint film and the substrate, making the paint film more stable and stronger.
