▎ 摘　　要

We study the elastic response of graphene nanomeshes based on molecular-statics and molecular-dynamics simulations of uniaxial tensile deformation tests. Elastic properties are determined as a function of the nanomesh architecture, namely, the lattice arrangement of the pores, pore morphology, material density (rho), and pore edge passivation, and scaling laws for the density dependence of the elastic modulus M, M(rho), are established. We find that, for circular unpassivated pores, M scales with the square of rho. Deviations from quadratic scaling are most strongly influenced by pore morphology and, to a lesser extent, by pore edge passivation and temperature. (C) 2014 AIP Publishing LLC.
