What is ‘graphene’?

A widely used antistatic agent designed to protect equipment and electronic parts and goods

Graphene, so-called ‘new wonder material’, is a single graphite layer of carbon atoms arranged in an interconnected honeycomb form. It is widespread in diverse fields such as semiconductors, displays and solar cells.

Features

Thickness Keeps its electrical properties even though the single carbon layer is bent or extended to 0.3nm (high specific surface area)
Strength 200 times greater than steel
Electrical Conductivity 100 times greater than copper
Electronic Mobility 100 times greater than silicone
Thermal Conductivity Twice as high as diamond

Manufacturing Method

Chemical Vapor Deposition (CVD)

Chemical Exfoliation

Electrical Decomposition

The graphene manufacturing method is divided into two parts: Physical exfoliation, chemical exfoliation.
Specifically, it includes chemical vapor deposition (CVD) which synthesizes graphene at high temperature using gas, chemical exfoliation in which carbon grows at high temperature according to crystals and electrical decomposition.
However, such chemical methods are high in manufacturing costs and cause environmental pollution.
At present, many businesses are producing and distributing graphene, using an oxidation process for its mass production and commercialization.
KB ELEMENT manufactures non-oxidized graphene, using physical exfoliation, not the chemical method.
