A copolymer composite of Zn-HNT/p(EDOT-co-EDOP) was deposited on low nickel stainless steel (LN SS) using an electrochemical polymerization method. The structure of the copolymer and the composite was confirmed by various analytical studies. In this work, the anticorrosion ability of the coatings was assessed in acidic solutions using an electrochemical method and their antibacterial activity was examined against marine bacteria.
