Angstron Materials (previously owned by Nanotek Instruments and now by Global Graphene Group and based in Ohio, USA) is developing and producing nano graphene platelets (NGPs), and also provide pristine graphite and single layer graphene.
Sweden-based Aninkco was established in August 2015 as spin-off from KTH Royal Institute of Technology. The company aims to develop and produce novel conductive inks based on graphene and other 2D materials.
In September 2017 Aninkco, together with KTH and Huawei Technologies Sweden received a $120,000 grant from SiO-Grafen - VINNOVA to develop a 3D printing technique to fabricate graphene-coated heat spreaders.
Applied Graphene Materials (previously Durham Graphene Science) was established in 2010 as a spin-off from Durham University to develop a new graphene synthesis method and produce graphene materials.
Avanzare is a supplier of high-performance nanomaterials for a wide range of applications.
The company produces graphene flakes and graphene oxide.
Be Dimensional is an Italian early-stage startup, spun off from the IIT scientific research centre.
BGT Materials Limited (previously BlueStone Global Tech) is a Manchester, UK based graphene producer. BGT offers high-quality, fully customizable graphene on several substrates (Quartz, Copper, Silicon and others). BGT Also offers a range graphene and graphene oxide based products, including suspensions, inks and membranes.
In September 2013 BGT announced plans to collaborate with Manchester University on several graphene projects, including research into supercapacitors, plasmonics and filtration membranes. BGT is the first industrial partner of the £60-million National Graphene Institute at the University of Manchester.
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.
Cambridge Nanosystems is a start-up company that was spun-off from the University of Cambridge with an aim to supply graphene materials (and also Single-Walled Carbon Nanotubes - SWCNT).
The company currently produces high quality (metal-free) graphene flakes (200-500 nm). The company's capacity is several kg/day, but it is building a new 5-ton factory.
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.
