Performance of Copper Corrosion Inhibitors on Pipecoridithiocarbamic Acid in 3 wt% NaCl Solution

Pipecolyldithiocarbamic Acid (PIPDTC) is actually considered as a potential corrosion inhibitor. The inhibition behavior of PIPDTC is appropriately confirmed by electrochemical measurements accompanied with spectra characterization techniques and DFT calculations. The consequences point out that chemically adsorbed PIPDTC molecule is an outstanding corrosion inhibitor with corrosion efficiency of 99.87% at 298 K and a great thermal stability ascribed to the Cu-S binding, implying that PIPDTC could be a tangible alternative as the prospective corrosion inhibitor for applications in marine industry.
