Electropolymerization of N-Salicyly tetrahydro phthalamic acid for anticorrosion and antibacterial action applications

Abstract

Poly (N-salicyly tetrahydrophthalamic acid) (PSP) synthesized from corresponding monomer N-salicyly tetrahydrophthalamic acid (NSP) in aqueous solution by using electrochemical polymerization process at room temperture. The polymeric film formed on stainless steel (316) surface (working electrode) and its structure examined by Fourier Transmission Infrared Region (FTIR). The anticorrosion action of the polymeric film on stainless steel (S.S316) was studied by using electrochemical polarization method in 0.2M HCl solution and temperature range (293-323)K. Kinetic and thermodynamic of activation parameters for corrosion process of S.S were calculated. The biological activity of polymeric film determined toward gram positive bacteria which is Staphylococcus aureus (Staph.Aure) and negative bacteria which is Escherichia coli (E.Coli). The effect of nanomaterials was studied by adding to the monomer solution in different concentrations to increase the efficiency of polymeric film as anticorrosion and antibacterial. The nanomaterials used in this study which are Graphene (G) and Zinc Oxide (nano) (ZnOn).

Corrosion Protection Performance of PACC and PACC-Metal Oxides Nanocomposites Electropolymerized Coating of Low Carbon Steel

“…Based on previous studies [19][20][21][22][23], the mechanism of the ACC monomer electropolymerization on the LCS electrode surface has been suggested according to cationic electropolymerization, which takes place in the stages described below [28,29]: 1. The working electrode accepts a single electron from the monomer molecule and a cationic radical is formed, as shown in steps 1 to 2 of Fig.…”

“…These compounds are selected based on their large molecular weight, functional polarity (such as -C=O, C=N), and extensive connections in aromatic rings, allowing them to adsorb on alloy surfaces [18]. There are many studies on the electropolymerization process to protect alloys from corrosion [19][20][21][22][23].…”

A novel long-acting antimicrobial nanomicelle spray

“…Polymethylmethacrylate polymer (PMMA) is a transparent polymer with low toxicity as it does not contain harmful subunits [11]. Moreover, this polymer exerts antimicrobial activity which leads to a desirable synergistic effect with the embedded antimicrobial materials [12].…”

“…Polymethylmethacrylate polymer (PMMA) is a transparent polymer with low toxicity as it does not contain harmful subunits. 11 Moreover, this polymer exerts antimicrobial activity which leads to a desirable synergistic effect with the embedded antimicrobial materials. 12 Furthermore, it has antifouling properties resulting in less accumulation of dirt on its surface, which, in combination with the transparent nature of PMMA, would lead to an elegant appearance after surface coating.…”
