Resumo:  Single layer graphene has been used as an additive in poly(butyl methacrylate-co-ethylene dimethacrylate) monoliths. Incorporation of the carbon sheets into the polymer matrix was achieved by simple admixing graphene into the polymerization mixture containing both monomers and porogens. Chromatographic experiments indicated that some of the graphene layers were located at the pore surface and increased the apparent hydrophobicity of the material. Raman spectroscopy of the polymer containing graphene documented a rather homogeneous distribution of the single layer graphene sheets over wide areas of the monolith. However, the spectroscopy also confirmed the presence of other areas where the graphene sheets interacted with each other and formed clusters.
