SMALL SCALE EFFECT ON THE BUCKLING ANALYSIS OF DOUBLE-LAYER GRAPHENE NANORIBBONS EMBEDDED IN AN ELASTIC MATRIX

摘要

A Graphene crystal is an infinite two-dimensional layer consisting of sp2 hybridized carbon atoms, which has sparked much interest. Graphene nanoribbons (GNRs), belonging to graphene sheets (GSs) and possessing large aspect ratio, have been a hot-spot because of their remarkable electronic, thermal and mechanical properties. There are some available methods to produce GNRs. Kosynkin et al. successfully synthesized GNRs by oxidative unzipping of carbon nanotubes (CNTs). Cai et al. devised a simple, bottom-up approach to produce GNRs with different topologies and widths. Sen et al. produced GNRs by tearing GSs from adhesive substrates, and discovered the formation of tapered GNRs.
