The green synthesis of nanoparticles using Costus pictus leaf extract blended with paint and its potential applications

Abstract

Nanoparticles are important due to their unique properties that may lead to new and exciting applications. Green synthesis has many advantages amongst physical and chemical methods of nanoparticle synthesis since the method is simple, inexpensive, and environmentally friendly. This research work describes the synthesis of carbon nanoparticles using leaf extract of Costus pictus and the characterization studies were carried out by Fourier Transform Infra-Red and Ultra Violet-Visible spectrophotometry. Incorporation of the nanoparticles of Costus pictus leaf extract into the paint formulation increases the corrosion protection properties. The inhibitive effects were investigated using weight loss, polarization, and impedance studies. The surface analysis techniques of Scanning Electron Microscope and Atomic Force Microscopy were used to investigate the morphology study. Findings show that synthetic nanoparticles mixed with paint function as more effective and thermally stable agents, serving as an alternative environmentally acceptable anticorrosion addition for cleaning and pickling processes in industries.
