BLACKLEAF is a France-based company that aims to make graphene affordable and enable the industry to reshape products with a greener and more efficient approach.
The company produces Few Layer Graphene (FLG) based on a proprietary method. BLACKLEAF says its process results in high quality materials that is dispersed in a 98% water-based solution.
Brazil-based Boomatech produces graphene, graphene oxide and r-GO materials. The company developed its own production (a mix of Hummers + Tours + proprietary knowledge). The company's GO production capacity is around 100 Kg per month.
Boomatech also develops graphene-based applications, currently focused on graphene batteries.
Founded in Sweden in 2017, Bright Day Graphene (BDG) strives to offer high performing materials without harmful environmental impacts.
US-based BuckyRing has developed a novel method of graphene production, which the company says is highly power efficient, environmentally friendly and safe.
BuckyRing provides single-layer graphene in dispersions in quantities suitable for research and development through production.
Carbon Gates Technologies (CGT) is an early-stage company that was spun-out of Texas A&M University in 2018.
CGT produces high quality graphene flakes (GNPs). The company says that its proprietary graphite exfoliation production process results in large graphene nanoplatelets, with very low D/G peak.
Carbon Nano-Material Technology is a South Korean refined graphite and graphene carbon materials manufacturer. It holds several patents and further patents pending relating to processes for the manufacture of these materials at significantly lower costs than other manufacturers.
The company is already said to be selling value added graphite products in the market using its proprietary portfolio of technologies. Carbon Nano-Material Technology has developed mass-production technology at a cost of 20 to 30% of existing technology in-house for the first time in the world by enhancing catalyst production and synthesis in the existing production process of carbon nano-material
