“…Protonated pyridinium's functional group is adsorbed at anodic sites to prevent iron dissolution and at cathodic sites to halt the hydrogen evolution reaction [43][44][45][46]. This implies that the anodic and cathodic partial responses are regulated by the CPC through a multimodal inhibitory mechanism [46][47][48][49][50][51][52][53]. The fact that the CPC molecules adhere to the mild steel surface implies that, depending on their concentration, they self-aggregate there to form a variety of stripes that are uniformly wide, regularly spaced, and well-organized.…”

The corrosion inhibition behavior of cetyl pyridinium chloride (CPC) on mild steel (MS) in 0.5 M H2SO4 solution was examined using the weight loss method and potentiodynamic polarization method. The experimented MS surface was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and Atomic Force Microscopy (AFM). Corrosion rate and corrosion efficiency was calsulated via weight loss and potentiodynamic polarization methods where the corrosion rate in 0.5 M H2SO4 , 0.000192 M, and 0.0077 M of CPC solution was 12.09×10-3, 8.23×10-3, 6.63×10-5 (mm/Year), respectively and the inhibition efficiency of 94.42% and 98.54%. FESEM studies demonstrated the corrosion attack on MS surface. Also, the EDX showed the presence of nitrogen of CPC. Thus, CPC acts as an important corrosion inhibitor.

“…Mahbub et al have examined the effect of aqueous alcohol (methanol and ethanol) solvent on CTAB-SDS mixed micelles. Recently, our research group investigated the solvency effect of TFE on the HEC-SDDS system to enhance the hydrophobicity of the medium . For nonionic surfactants, cloud point (CP) is the most important physical parameter.…”

The influence of 2,2,2-trifluoroethanol (TFE) on the micellar properties of ionic surfactants hexadecyltrimethylammonium bromide (CTAB), hexadecyltrimethylammonium ptoluenesulfonate (CTAT), sodium dodecyl sulfate (SDS), Nlauroylsarcosine sodium salt (SDDS), and nonionic surfactant Triton X-114 (TX-114) in aqueous solutions was studied using tensiometry, electrical conductivity, fluorimetry, time-resolved fluorescence, and microcalorimetry. With increasing concentrations of TFE, the micellar charge densities of the ionic head groups decrease, causing a decrease in the critical micelle concentration (CMC) of ionic-surfactant solutions (SDS, SDDS, CTAB, and CTAT) in micellar solutions. However, for nonionic surfactant TX-114, the polar headgroup undergoes some conformational changes causing an increase in the value of CMC. Time-resolved fluorescence decay measurements were done to get evidence of penetration of TFE molecules into the stern layer of the micelle. The micellar aggregation number declines with increasing concentration of solvent, indicating a higher concentration of mixed solvent reducing the number of monomers needed for micellization for ionic surfactants, whereas for nonionic TX-114, it indicates some structural changes of the molecule forming the micelle in the presence of TFE.
