Graphene Nanochem was a UK-based company with Malaysian ties that manufactures performance specialty chemicals and advanced nanomaterials from renewable sources including waste materials. The company offered several products for the oil and gas sectors.
Graphene Nanotech (GPNT) was a Spanish startup that aimed to develop products based on epitaxial graphene grown on SiC (silicon carbide) substrates.
The company was collaborating with several Spanish research institute - CSIC (Spanish National Research Council), CNM (National Microelectronics Center), UNIZAR (University of Zaragoza), INA (Institute of Nanoscience of Aragon) and the ICMA (Materials Science Institute of Aragon).
Graphene Platform Corp (previously iTRIX), established in 2000 and based in Tokyo, Japan refocused its business to graphene in 2011. The company maintained a fully equipped applications lab in Yokohama, Japan and produced CVD graphene and epitaxial graphene on SiC for both commercial and R&D use.
Graphene Security, spun-off from BGT Materials (previously BlueStone Global Tech) was a Manchester, UK based company that aimed to produce graphene-based solutions for security applications.
Its RFID tags and antennae, printed with graphene-based inks, were showcased at the 2016 MWC in Barcelona. In March 2013, the company announced its first commercial order for RFID antennae.
Graphene Sensors was established in 2011 in Canada, with an aim to commercialize graphene-based sensors for the medical market.
The company announced its GS7 biosensor technology (for the early detection of potentially cancerous cells), and also announced evelopment of chemical sensors. In May 2015 the company announced a $36 million Joint-Venture with Meditel to commercialize the GS7 sensors.
Graphene Technologies, founded in 2007 and based in Novato, California, developed a unique, patented and eco-friendly way to synthesize graphene (and other carbon-based materials) from carbon dioxide (CO2).
In July 2014, Graphene Technologies signed an agreement with Stratasys to co-develop graphene-enhanced 3D printing materials. In 2016 the company changed its focus to development of graphene-based foams.
GRPAHENEALL was a producer of graphene materials, with a plant in Siheung, Korea. Since its start-up phase in July, 2012, GRAPHENEALL has been focusing on the commercialization of chemically exfoliated graphene raw material. Grapheneall manufactured Graphene oxide(GO) and Reduced Graphene Oxide(rGO), on a self-reported ton per month scale.
The company no longer seems to be in business.
GraphenEra was a joint venture company owned by LWP Technologies (ASX:LWP) and VVV Technologies to build a proprietary designed aluminium graphene oxygen battery prototype that will aim to have vastly superior features compared to current Lithium based batteries.
GrapheneTech (owned by Eficiencia Energtica Aplicada) was a Spain-based company, focused on manufacturing graphene flakes (GNPs). The company specialized in producing graphene on a large scale for different industrial applications using a patented method that allows it to offer prices adapted to industrial needs, contrary to complex and costly methods.
In 2013, the company initiated a pilot plant for industrial production from the technology developed by its R&D team.
