Graphenea is a private European company (based in Spain) focused on the production of high quality graphene for industrial applications. The company produces single-layer graphene sheets, bi-layer graphene, multi-layer graphene, graphene oxide and other materials - on any substrate the customer provides.
3D Graphtech Industries was established in 2014 by Kibaran Resources and 3D Group to research and develop graphite and graphene applications for 3D printing. 3D Graphtech sources its graphite exclusively from Kibaran's Tanzanian graphite mine.
Since its establishment, 3D Graphtech did not release any information and the company does not have a web page.
Adama Materials has developed a family of graphene oxide toughening agents for epoxy, unsaturated polyester, and vinyl ester resins.
Adama reports that its toughening agent can double resin toughness and deliver anywhere between a 60% and 140% increase in fracture energy (G1c) without losing composite strength or modulus.
Applied Nanotech is a PEN company and functions as the PEN Design Center focused on developing new products for the PEN family of companies using nanotechnology approaches. Its team of PhD level scientists and engineers works with companies to solve technical problems and create innovations, producing a competitive advantage for the PEN family.
Applied Nanotech was founded in 1989, went public in 1993, and for the majority of its history focused on next generation display applications. However in late 2005, to diversify from one "make or break" technology, it expanded its focus to other areas leveraging its previous work. From 2006 to the present, it has made substantial progress in these areas. The company has organized its efforts into four divisions each of which has substantial potential: Nanomaterials, Nanoelectronics, Nanosensors, and Nanoecology.
Beijing Carbon Century Technology, founded in 2013, specializes in graphene macro preparation technology, R&D and technical services of its downstream application technology. Beijing Century Carbon has been identified by the ISO9001 , ISO14001 certification, and passed the identification of high-tech enterprise.
CalBattery is a Los Angeles based start-up that develops silicon-graphene lithium-ion battery anode material.
Dongxu, also known as Tungshu, was established in 1997 and its headquarters and R&D center are located in Beijing. With roots in the optoelectronic display industry, it now has become a industrial investment enterprise focused on the optoelectronic display and renewable energy industries, while also covering financing, urbanization and real estate.
Israel-based Dotz Nano was established in 2014 to commercialize a graphene quantum dot production process developed at Rice University's Tour Labs.
Dotz Nano's vision is to be the premier producer of GQD’s by producing and supplying high quality GQD’s for use in various applications including medical imaging, sensing, consumer electronics, energy storage, solar cells and computer storage.
