The role of internal intensifier microemulsion for monitoring acid anti-corrosion activity of enhanced cinnamaldehyde contained-PMMA nanocolloid in industrial pipeline simulations

The quest to replace toxic and hazardous chemicals in the nearest future in all industrial pipelines are interested to revolutionize the anti-corrosion material research world by turning its attention to green formulations based on the nanotechnology. Herein, we report a new combination of corrosion inhibiting potential of cinnamaldehyde contained Poly(methyl methacrylate) nanocolloid and KI internal intensifier mixture on the corrosion of C1018 steel in 3 Wt.% HF and 15 Wt.% HCl solution. KI internal intensifier was prepared by water-in-oil microemulsion and was characterized wit Dynamic Light Scattering (DLS) analysis and the average particle size of KI internal intensifier containing surfactant-based microemulsion was 73 ± 2 nm. We also report the effect of the inhibitor concentration, types of steel alloy, intensifier additive concentration, as well as temperature on the corrosion inhibiting performance of corrosion inhibitor + KI microemulsion mixture. corrosion inhibitor + KI microemulsion mixture exhibits inhibiting ability but the extent of inhibition is dependent on concentration, temperature, and intensifiers’ concentration. The adsorption of cinnamaldehyde contained polymer + organic sulfur compound + KI internal intensifier is synergistic in nature. Increase in the temperature study resulted in a slight decline in the inhibition efficiency of corrosion inhibitor + KI with efficiency of above 95% achieved at 343 K and inhibition efficiency by amine film forming on the surface of alloy was confirmed with Atomic Force Microscopy (AFM) and compared to uninhibited alloy sample.
