Patent abstract
A method of exfoliating layered, shearable material is described. Examples are provided including exfoliation of graphite to form graphene nanoplatelets. Also described is a machine for preparing nanoplatelets that includes a chamber whose volume can be increased by pressure exerted by the exfoliated product. Composites of graphene nanoplatelets and polyamide exhibited improved flexural modulus compared to that of graphite composites while impact strength was unaffected.
