Article Synopsis
  • - Surfactants are recognized for their ability to prevent corrosion by interacting with metal surfaces, but their effectiveness is limited due to their small size and required high concentrations in aqueous environments.
  • - Polymeric surfactants have emerged as promising corrosion inhibitors, offering improved performance due to their larger molecular structure, strong bonding capabilities, and the presence of polar functional groups that enhance their solubility in industrial electrolytes.
  • - The text discusses the advantages and challenges of polymer surfactants, including their industrial applications, colloidal properties, and how they serve as a modern alternative to traditional corrosion inhibitors.

Coronavirus disease-2019 (COVID-19), associated with the outbreak of deadly virus originating in Wuhan, China, is now a global health emergency and a matter of serious concern. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is rapidly spreading worldwide, and WHO declared the outbreak of this disease a pandemic on March 11, 2020. Though some of the countries have succeeded in slowing down the rate of the spread of this pandemic, most the countries across the globe are still continuing to experience an increasing trend in the growth and spread of this deadly disease.

Polyurethane based tri-block copolymers namely poly(N-vinylpyrrolidone)-b-polyurethane-b-poly(N-vinylpyrrolidone) (PNVP-PU) and poly(dimethylaminoethylmethacrylate)-b-polyurethane-b-poly(dimethylaminoethylmethacrylate) (PDMAEMA-PU) were synthesized through atom transfer radical polymerization (ATRP) mechanism. The synthesized polymers were characterized using nuclear magnetic resonance (NMR) spectroscopy and gel permeation chromatography (GPC) methods. The corrosion inhibition performances of the compounds were investigated on mild steel (MS) in 0.
