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.
