What is ‘Non-oxidized Graphene Powder’?

2-dimensional graphene created by exfoliating the graphite layer of carbon atoms one by one, using the physical method

Non-oxidized graphene is 2-dimensional graphene created by exfoliating the graphite layer of carbon atoms one by one, using the physical method.
Skipping an additional chemical process, it keeps the intrinsic properties of graphene without any physical or chemical defect.
Thanks to its excellent mechanical, electrical and thermal properties, non-oxidized graphene has been used in various fields including secondary battery, super capacitor, heat dissipation, semiconductor and defense industry.

What is ‘graphene nano-platelet (GNP)’?

An intermediate acquired during the manufacture of graphene; multilayer structure with less than 100 nanometers in thickness

Graphene nano-platelet (GNP) is an intermediate acquired during the manufacture of graphene. It is multilayer-structured with less than 100 nanometers in thickness.
Retaining the great properties of graphene, GNP is smaller than graphene in terms of the specific surface area. Therefore, it has been available as a filler of heat-dissipation materials.
Thanks to low density, in addition, it is commonly used in various fields such as aircrafts, secondary batteries and electric vehicles.
