Deformation and perforation of graphene nanoparticles

摘要

As a multilayer sheet of graphene material, a multilayer sheet of graphene material having a plurality of voids extending therethrough is described. There is also provided a method of making the sheet, comprising exposing a graphene material comprising multi-layer graphene having from 2 to 10 graphene layers to a particle beam comprising nanoparticles, wherein the nanoparticles comprise nanoparticles Have an energy of at least 2 keV per molecule.
