“…The ethylenediamine cored imidazoline based dendrimeric polymer with four terminal imidazole rings, tetra-imidazoline (DDTI) was synthesized and investigated as good corrosion inhibitor for carbon steel in CO 2 medium using weight loss, PDP, EIS and SEM methods [37]. Results manifested that the DDTI acts as good corrosion inhibitor for carbon steel and showed the optimum inhibition efficiency of 98.29% at 400 mg L -1 concentration.…”

Dendrimers are a new class of highly branched, nano-sized, monodisperse macromolecules that have several fascinating physical and chemical characteristics. They are highly soluble in the polar solvents, contain several surface functionality and high surface area which makes them suitable reagents for industrial and biological applications. Recently, several dendrimers have been investigated as effective corrosion and scale inhibitors for metallic and silica corrosion using experimental and theoretical methods. Generally, dendrimers become effective by forming insoluble metal-dendrimer or silica-dendrimer composite on the surface. Their inhibition performance of dendrimers have been measured using several experimental such as weight loss, electrochemical (EIS and PDP) and surface (EDX, SEM and AFM) as well as computation techniques such as molecular dynamics simulation and DFT based quantum chemical calculations. The interactions between metal surface and dendrimers can be explain through some common parameters such as E HOMO , E LUMO , ∆E, electronegativity (χ), hardness (η), softness (σ), dipole moment (µ) and fraction of electron transfer (∆N). Present book chapter deals with detail description on the corrosion inhibition and anti-scaling behaviours of dendrimers for metals and silica in several electrolytic media.

“…Massive costs are invested to manage corrosion in the oil and gas industry. The strategies consist either in using corrosion resistant alloys or the use of steel with corrosion inhibitor [6,7]. DANAEE, BAHRAMIPANAH Inhibition of organic compound inhibitors occurs due to interaction between inhibitor molecules and the metal surface via adsorption.…”

The inhibition ability of N,N '-bis(2,4-dihydroxyacetophenone)-1,3-propandiimine (DHAPP) as a schiff base against the corrosion of API-5L-X65 in 1 M HCl solution was evaluated by polarization, electrochemical impedance spectroscopy, and scanning electron microscopy. Polarization studies indicated that DHAPP retards both the cathodic and anodic reactions through chemical adsorption and blocking the active corrosion sites. The adsorption of this compound obeyed the Langmuir adsorption isotherm. The inhibition effi ciency increased with inhibitor concentration and decreased with increasing temperature. EIS data analysed to equivalent circuit model showed that as the inhibitor concentration increased the charge transfer resistance of steel increased whilst double layer capacitance decreased. Kinetic and thermodynamic parameters such as activation energy, enthalpy, entropy, and Gibbs free energy of activation and adsorption were calculated. Gibbs free energy indicated that adsorption occurred through physical and spontaneous process. Scanning electron microscopy was used to study the steel surface with and without inhibitor.The inhibition ability of N,N '-bis(2,4-dihydroxyacetophenone)-1,3-propandiimine (DHAPP) as a schiff base against the corrosion of API-5L-X65 in 1 M HCl solution was evaluated by polarization, electrochemical impedance spectroscopy, and scanning electron microscopy.

“…So, the search for green polymers or biopolymers has been sought worldwide. Several polymers have been studied with heteroatoms in their structures [11][12][13][14][15]. The multifunctional groups in the polymers can easily adsorb or attach to any metal surface, thereby protecting them from corrosion.…”

Anti-Corrosive Properties of an Effective Guar Gum Grafted 2-Acrylamido-2-Methylpropanesulfonic Acid (GG-AMPS) Coating on Copper in a 3.5% NaCl Solution

Guar gum grafted 2-acrylamido-2-methylpropanesulfonic acid (GG-AMPS) was synthesized using guar gum and AMPS as the base ingredients. The corrosion inhibition of copper was studied using weight loss, electrochemical, and surface characterization methods in a 3.5% sodium chloride (NaCl) solution. Studies including weight loss were done at different acid concentrations, different inhibitor concentrations, different temperatures, and different immersion times. The weight loss studies showed the good performance of GG-AMPS at a 600 mg/L concentration. This concentration was further used as the optimum concentration for all of the studies. The efficiency decreased with the rise in temperature and at higher concentrations of acidic media. However, the efficiency of the inhibition increased with the additional immersion time. Electrochemical methods including impedance and polarization were employed to calculate the inhibition efficiency. Both of the techniques exhibited a good inhibition by GG-APMS at a 600 mg/L concentration. Surface studies were conducted using scanning electrochemical microscopy (SECM), scanning electron microscopy (SEM), and atomic force microscopy (AFM) methods. The surface studies showed smooth surfaces in the presence of GG-AMPS and rough surfaces in its absence. The adsorption type of GG-AMPS on the surface of the copper followed the Langmuir adsorption model.
