Schiff bases are effective corrosion inhibitors for metals like mild steel, copper, and aluminum, offering high efficiency, adaptability, environmental stability, and cost-effectiveness. This study examines how substituents and molecular structures influence their corrosion-suppressing capabilities. It also analyzes the effects of metals and environmental factors such as temperature and pH on their performance. The relationship between inhibition efficiency and Schiff base concentration is explored to provide insight into their protective mechanisms. Industrial applications are discussed, particularly in coatings, mechanical engineering, and the oil and gas sectors. A key focus is on integrating nanotechnology into Schiff bases to enhance their protective properties. Innovations like nanoscale surface treatments, controlled release via nanocapsules, and nanocomposite coatings are highlighted as promising advances for next-generation corrosion prevention. The study emphasizes the need for future research into environmentally sustainable Schiff bases, novel derivatives with enhanced characteristics, and extensive industrial testing. The integration of nanotechnology is identified as a critical area for development, potentially leading to more effective and durable corrosion prevention solutions. These advancements position Schiff bases as a versatile and sustainable choice for industrial corrosion control.
