CTDAT
CTDAT was launched in 2014 in Mexico as a consultancy firm that specializes in graphene production technologies. CTDAT developed a patent-pending process to exfoliate graphene from graphite.
The company is able to produce graphene oxide and reduced graphene oxide from ore mineral graphite. CTDAT is a private company with close contact with Arizona University, UNAM and UNISON. It seems that the company is no longer in business.
