Angstron Materials has received United States patent 8,114,373 for its next-step method that effectively exfoliates layered graphene and offers several key advantages.
According to Angstron, the method is able to produce nano graphene platelets with a thickness thinner 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, it says 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.
