Preparation of Fe2O3 nanoparticles by acoustic and hydrodynamic cavitation techniques and corrosion inhibition release studies using its nanocontainers

Abstract

The present work deals with two parts, the first one deals with the synthesis of Fe2O3 nanoparticles using acoustic and hydrodynamic cavitation techniques and the second one deals with layer by layer (LBL) assembly of Fe2O3 nanocontainers by loading a corrosion inhibitor, benzotriazole, in polyelectrolyte layers. The nanoparticles obtained from both these techniques are used as a core in the preparation of nanocontainers. The morphology of the nanoparticles and nanocontainers was analyzed by TEM. The release rate and corrosion inhibition properties of nanocontainers were evaluated for various prepared samples. Electrochemical impedance test and corrosion inhibition performance of Fe2O3 nanoc..
