In this work, a new monolithic stationary phase containing multi-wall carbon nanotube (MWNT) was prepared by in situ polymerization of acid-treated MWNT using glycol methacrylate as monomer and ethylene dimethacrylate as the crosslinker on a silanized capillary.Morphology of the novel stationary phases was studied by scanning electron microscopy.While the surface of the column containing MWNT was rather irregular, the surface of the bare column was relatively round and smooth.The SEM micrographs indicatedthat MWNT had great influence on the morphology of the monoliths.
