| Abstract | ||||
| New graft co-polymer nano-particle (coating nano-polymer) was prepared as a corrosion inhibitor in 1M sulfuric acid. The synthesized coating nano-polymer was characterized by FT-IR, 1H NMR and atomic force microscope (AFM). Synthesized coating nano-polymer mixed with acrylic acid in different proportion (0.2-0.8 mole: 293K: 30 min). Potential-dynamic polarization technique is used to get current corrosion, inhibition efficiency, cathodic and anodic Tafel slopes with examination of concentration influence on inhibition efficiency, the results revealed that the inhibition efficiency increases as inhibitor concentration increases. The maximum inhibition recorded efficiency 93% at 0.8 mol. | ||||
