ABSTRACT
Corrosion is first and foremost a safety risk which has to be understood and managed.
In this study a highly water-repellent hydrophobic coating was synthetized to protect carbon steel petroleum pipelines from corrosion. To achieve this target, (styrene-vinyl acetate) denoted as P(St-VAc) (E1, E2 and E3) copolymers of different molecular weights and different monomer molar ratios were synthesized. The chemical structures of the prepared copolymers were elucidated by FT-IR, and ¹H-NMR spectroscopy. The molecular weights of the prepared copolymers were determined using GPC. The wettability of the prepared coating films and the value of Ra (arithmetic mean roughness)were measured via contact angle and confirmed by AFM techniques. Different factors affecting the efficiency of prepared materials in corrosion inhibition e.g. i) Concentration of the coating solution ii) Temperature iii) Activation energy iv) Contact angle; were studied.
