PVP-Oxime-SiO2- Adenine, Antibacterial and Anticorrosive Behavior

Abstract

As nanotechnology developed, the chemical architecture of materials was modified. Our study aims to develop nanohybrid sol-gel processes comprising silica particles and a polymer resin, including functionalized carboxylic groups (typically epoxy or phenolic resins). A film of ceramic glass is formed when the metallic plate is coated. It is possible to obtain corrosion-resistant properties by incorporating these particles into polymeric matrixes. Researchers studied infrared spectroscopy and scanning electron microscopy to determine the structure of RF refers to phenolic resin, RFF refers to resin functionalized, and RF-SIO₂ and RFF-SIO₂ refers to their respective hybrids. As a result of polarization, Polyvinylpyrrolidone (PVP) appears to act like a mixed-type inhibitor. The charge transfer process is largely responsible for preventing corrosion of the C-steel. Using weight loss as a measure of inhibitory efficacy ranged from 56 to 83% while using electrochemical methods, it was 60 to 90%. PVP adheres to steel and prevents corrosion, according to different tests. The Langmuir adsorption isotherm is found to govern PVP adsorption on the C-steel surface. An explanation for PVP's inhibitory action is suggested. A thermodynamic parameter Eapp is determined by the adsorbed PVP on the C-steel surface, *H, and *S decrease. As inhibitor concentration and temperature increase, so does PVP's inhibition efficiency.
