Abstract
The invention provides a method for preparing a Polyurethane-Carbon Nanotube (PU-CNT) based coating composition. More specifically, the invention provides a method for preparing a PU-CNT based anti-corrosive coating composition. The method comprises preparing a dispersion comprising one or more types of Carbon Nanotubes (CNTs). The dispersion is prepared by dispersing the one or more types of CNTs in a dispersant comprising at least one polar solvent and at least one surfactant. The method further comprises mechanically mixing a hardener with the dispersion comprising the one or more types of CNTs. In addition, the method comprises mechanically mixing polyurethane with the dispersion prepared by mechanically mixing the hardener with the dispersion comprising the one or more types of CNTs.
