Abstract
In recent years, application of nanoparticles in various fields of physical science and natural science receiving tremendous attention from researchers. Nanoparticles can offer significant advantages in terms of high stability, enhanced mechanical properties, and high surface area to volume ratio. This work attempts to explore these noble characteristic properties of nanoparticles for preservation for materials of engineering applications. Nanoparticles of maltodextrin (MLD-Np) were prepared by microwave-mediated nanoprecipitation technique. Characterization was done by spectral, zeta potential measurement, X-ray studies, Scanning Electron Microscope (SEM) and Transmission Electron Microscopy (TEM) analysis. In the second part, these nanoparticles were tested for their surface protection ability due to interfacial adsorption. Corrosion inhibition study measurements were done by electrochemical methods, and interfacial adsorption of inhibitor was established by studying surface morphology. The efficacy of these nanoparticles was 93% for the addition of 50 ppm of it. In the last part of this work, an attempt is made to compare the inhibiting ability of various reported chemical inhibitors for acid corrosion of zinc with synthesized nanoparticles. Nanoparticles of maltodextrin emerged as an appreciably good green corrosion inhibitor with environmental and economic benefits.
