Abstract: Polypyrrole/SiO₂ nanocomposite doped with 3-nitrosalicylic acid was synthesized in three concentrations of 3-nitrosalicylic acid: 0.01 M, 0.005 M, and 0.0025 м. FTIR spectroscopy, thermogravimetric analysis (TGA), Raman scattering spectroscopy, and FESEM imaging further assisted in determining the shape and structure of the polypyrrole/nanocomposite product. The aluminum protection arrangement of the paint film comprising polypyrrole/SiO₂ nanocomposite doped with 3-nitrosalicylic acid was proven by electrochemical methods. The salt spray test results also demonstrated the protective efficacy of the paint film comprising polypyrrole/SiO₂ nanocomposite doped with 3-nitrosalicylic acid to suppress corrosion. The best corrosion prevention results were obtained with a polypyrrole/SiO₂ nanocomposite dispersion paint film doped with 0.01 м 3-nitrosalicylic acid at a concentration of 2%.
