We thank P. Ordejon, J.J. Palacios, J. Fernandez-Rossier and G. Montambaux for fruitful discussions. J.-C.C., N.L., and A.L. acknowledge financial support from the F.R.S.-FNRS of Belgium . This work is directly connected to the Belgian Program on Interuniversity Attraction Poles (PAI6) on Quantum Effects in Clusters and Nanowires, to the ARC on Graphene StressTronics sponsored by the Communauté Française de Belgique, to the European Union through the ETSF e-I3 project (Grant nr 211956 ), and to the NANOSIM-GRAPHENE project (Projet nr ANR-09-NANO-016-01 ). Computational resources were provided by the CISM of the Université catholique de Louvain: several numerical simulations have been performed on the GREEN and LEMAITRE computers of the CISM. F.O. would like to thank the European Commission for a Marie Curie Fellowship .

N2 - The present theoretical review puts into perspective simulations of quantum transport properties in disordered graphene-based materials. In particular, specific effects induced by short versus long range scattering on the minimum conductivity, weak (anti-)localization, and strongly insulating regimes are discussed in depth. Using various types of disorder profiles (random fluctuations of the local impurity potential, long range Coulomb scatterers or more intrusive chemical functionalizations), universal aspects of transport as well as novel features in chemically modified graphene-based materials are depicted, especially in the cases of oxygen and hydrogen atoms adsorption. Finally, our theoretical results are compared to experimental measurements.
