pH-Responsive Smart Polymer Nanocomposites for Anti-Corrosive Coatings
Abstract: Metallic corrosion under adverse marine and industrial conditions imposes gigantic financial burdens and risks worldwide. Conventional waterproofing waterborne epoxy has passive barrier protection, but is also inherently microporous, lacking intrinsic repair ability against mechanical damage and thus rapidly decays. This is a critical gap that this work tries to bridge by designing a new pH-responsive hybrid polymer nanocomposite by using polyethyleneimine-tannic acid-cerium functionalized boron nitrate nanosheets with chitosan-capped mesoporous silica …

Development of Biomass-Derived Composites From Commodity Plastics Via Pyrolysis For Enhanced Corrosion Protection of Metals
Abstract: Escalating environmental concerns and the depletion of fossil resources have spurred the need for sustainable and eco-friendly materials. By converting plastic waste into valuable carbonaceous materials via pyrolysis, both plastic pollution and resource scarcity can be addressed. The process involves the thermal decomposition of plastics in an inert atmosphere, producing a mixture of gases, liquids, and solid residues rich in carbon. These carbonaceous residues are then incorporated with biomass materials …

Inhibitory Potentials of Datura Metel to Prevent Mild Corrosion
Abstract: The resistance of mild steel to corrosion was evaluated by immersing it in well water and determining the weight it lost after being allowed to return to room temperature after the submersion. The effectiveness of mild steel's ability to withstand corrosion was evaluated using this approach. A reduction in total body mass has an influence that is connected to and helps play a role in the prevention of rusting from …

Polymeric Coating Applied for Corrosion Protection of Mild Steel in Corrosive Medium
Abstract: Mild steel is coated with a polymer layer of polybutadiene for protection. However, this coating does not effectively safeguard the metal in environments containing moisture, sulphur dioxide, or chloride. These pollutants interact with the polybutadiene-coated surface, creating a highly corrosive atmosphere. Moisture condenses on the coated metal surface and absorbs sulphur dioxide, forming sulphuric acid. This acid initiates both chemical and electrochemical reactions with the polymer-coated metal, accelerating the corrosion …
