A review of dispersion of nanoparticles in cementitious matrices: Nanoparticle geometry perspective (2017, background): “Functionalization is a chemical treatment carried out by the means of neat acids, such as H 2 SO 4 and HNO 3 [51, 52], which results in a covalent bonding between hydroxyl or carboxyl groups with the CNT surface as a result of oxidation.”
