Gnanomat, based in Madrid, Spain, developed a proprietary patented liquid-phase procedure to exfoliate graphite to graphene. The single-step process produces high-quality graphene micro platelets. The process uses cheap, biodegradable solvents.
The company seeks to find industrial partners to license the technology and scale it to an industrial scale. In February 2017 Gnanomat signed an agreement to co-develop nanomaterials (including graphene) for batteries.
Strategic Energy Resources (SER) is an Australian based explorer with a diversified portfolio of mineral assets. The company is exploring and developing land with prospective large discoveries in Western Australia, South Australia and Victoria.
Future Carbon, based in Germany, develops and manufactures carbon nanomaterials and carbon composites.
In April 2013, Future Carbon acquired several graphene and CNT related patents from Bayer, but the company did not update on its graphene R&D work since.
Valence Industries is an Australian industrial manufacturing company that produces high grade flake graphite products.
In March 2014 Valence launched the Graphene Research Centre in collaboration with the University of Adelaide.
Oxford Advanced Surfaces Group, based in the UK, designs, develops and manufactures advanced materials for surface modification, adhesion promotion and nano-material applications based on its highly reactive chemical core platform technology called Onto.
In March 2014, OASG announced that it is investigating the use of its Onto technology platform to chemically functionalize graphene. In 2020 the company announced a collaboration project with 2-DTech.
Sony, based in Japan, is one of the leading consumer electronics companies in the world. Sony is developing graphene technologies - including a roll to roll production process that can produce graphene sheets up to 100 meters in length.
