Article Synopsis
  • Asphalt is widely used for its strong adhesion and affordability, but it lacks effective corrosion protection, requiring improvements through additives.
  • In this study, a poly(amidoamine)-zinc oxide (PAMAM-ZnO) nanocomposite was blended into asphalt, with a 2% ratio showing an exceptional corrosion protection efficiency of nearly 98% and a significant increase in charge transport resistance.
  • The corrosion protection mechanism relies on a protective barrier formed by PAMAM-ZnO and the sacrificial action of ZnO, which interacts preferentially with corrosive agents, thus enhancing the effectiveness and durability of the asphalt coating.

The detection of N-hexanoyl-l-homoserine lactone (C-HSL), a crucial signal in Gram-negative bacterial communication, is essential for addressing microbiologically influenced corrosion (MIC) induced by sulfate-reducing bacteria (SRB) in oil and gas industries. Metal oxides (MOx) intercalated into conducting polymers (CPs) offer a promising sensing approach due to their effective detection of biological molecules such as C-HSL. In this study, we synthesized and characterized two MOx/polyaniline-dodecyl benzene sulfonic acid (PANI-DBSA) nanocomposites, namely ZnO/PANI-DBSA and FeO/PANI-DBSA.
