“…Clay-conductive polymers are a relatively new class of composite materials that have been recently used as an anti-corrosive protective coating [11,12], because of their unique chemical and physical properties. The most popular conductive polymers are; polythiophene [13], polyaniline [14], and polypyrrole (PPy) [15], especially PPy is an ideal electroactive polymer to design smart coatings because of its easy preparation, biocompatibility and antioxidant properties [16][17][18][19]. Previous studies show that PPy could act as a physical barrier to prevent aggressive chemical reactions [20], as well as polymeric inhibitors leading to lower corrosion rate of iron [21].…”

In this work, a novel and cost-effective bentonite intercalated with polypyrrole Zinc oxide-silver nanocomposite (B-PPy/ZnO) hybrid material was prepared via in situ photopolymerization of pyrrole in the presence of silanized bentonite and zinc oxide nanoparticles and using silver nitrate as an initiator. The as-prepared Bentonite-polypyrrole/ZnO hybrid material was found to be black, exfoliated with a polypyrrole-rich surface decorated with ZnO and silver nanoparticles in a metallic state. We evaluated the propensity of the prepared hybrid material as an eco-friendly, anticorrosive, and antibacterial coating for carbon steel. The corrosion resistance efficiency study of B-PPy/ZnO composite incorporated with the epoxy matrix was carried out in a 3.5 % NaCl solution. B-PPy/ZnO 4 wt% composite coating on carbon steel was observed to exhibit best corrosion protection property, with High charge transfer resistance were value (9.85 MΩ cm − 2) compared to 0.213 MΩ cm-2 in the presence of pure epoxy. Cytotoxicity assay was carried out on an A549 epithelial cell line. Moreover, B-PPy/ZnO showed a reduction in Escherichia coli bacterial growth by ~86 % with a minimum inhibitory concentration of 0.03 mg ml-1. The results obtained herein will open new routes to the preparation of efficient ecofriendly anticorrosion and antibacterial coatings.
