Nano Reactive And Nonreactive Polymers As Asphalt Modifiers For Anticorrosion Application, Elsayed Elnaggar, Hesham Nassar, Mohamed Migahed, Gamal Elkady, Hazem Elsherif, Amina Saleh

Al-Azhar Bulletin of Science

Anti-corrosive coatings for carbon steel were formulated using modified asphaltic materials. Nanoparticles of polyaniline (PANI-HCl) were prepared by template free polymerization method and compared with low-density polyethylene (LDPE) as a nonreactive polymer. FT-IR proved the formation of polyaniline and XRD demonstrated a relative crystalline structure of the polymer while SEM showed fibrous nano morphology. The two types of modifiers were mixed with asphalt of type 85/25 in different percentages. SEM proved that polymer content of 4%, for both polymers, represented the most homogeneous polymer distribution in the bitumen as the continuous phase. Asphalt modification with LDPE yielded the largest values …
