. The polymer is synthesized at different molecular weight. Notably, gives
high inhibition efficiency even at low concentration. The corrosion inhibition capability of the polymer is due to the adsorption
of its function groups at the C-steel surface. The conjugation resulted from the indole/thiophene ring play an important role for
improvement the inhibition efficiency. The structure of polymer had been approved by NMR and IR. The type of adsorption of
the polymer was elucidated by different adsorption isotherms. FTIR analysis was performed to confirm the adsorption between
the polymer and C-steel surface. The morphological changes on the surface of steel were monitored by Scanning Electron
Microscopy (SEM).
