Toward New Application for Asphalt using Nano Technology

Although asphalt has a water repellent characteristics and can act as a protective coating through its barrier effect which is the first mechanism of corrosion control by coating, but it is not used in this purpose in industrial applications. In the same time, nano conducting polymers especially polyaniline can acts as anticorrosive pigment through its sacrificial effect which is the second mechanism of corrosion control. This work offers a novel and effective anticorrosive coating has the two mechanisms of corrosion control, barrier and sacrificial, through modification of asphalt by nano polyaniline based polymers and evaluation of these materials as anticorrosive coatings.
