Angstron Materials (Dayton, Ohio) has received United States patent 8,114,373 for its next-step method that effectively exfoliates layered graphene and offers several key advantages. The method is able to produce nano graphene platelets with a thickness less than 100nm and in many cases thinner than 10 nm or as thin as 0.34 nm to 1.02 nm. This method allows the NGP material to be used in applications ranging from bucky paper, mat, thin film and lamina to nanocomposites.
Suited to carbon- or graphene-based layered materials, this process does not use undesirable chemicals, time-intensive wash steps or require high exfoliation temperatures. In addition, the method does not produce contaminated waste water and its associated disposal costs.
Angstron Materials is the world’s largest producer of nano graphene platelets (also called NGPs) and the only manufacturer able to produce pristine graphene. Angstron offers six different graphene products, both oxide and pristine, in varying thicknesses and dimensions. The manufacturer also works with companies and researchers to select the right material, functionalize it and gain access to critical process efficiencies. These steps dramatically reduce the risk associated with innovative product development.
