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.
|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|
Chemical Vapor Deposition (CVD)
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.
|Non-oxidized Graphene||Graphene Oxide|

|Lateral size||1.0 ~ 3.0 μm||< 1.0 μm|
|ID / IG||< 0.18||< 1.0|
|Oxygen content (%)||< 6||> 24.6|
|Electric conductivity||104 S/m||When reduced: 102 S/m|
