The potential of Cocos Nucifera leaf as green corrosion inhibitor of copper.

Copper conductor has been extensively used in several application due to its high conductivity and hardness. However, copper corrosion which occurs in electrical power equipment results in corrosion-related failures. The demand for increased corrosion resistance of the impregnated electrical equipment is increasingly emerging from manufacturers. This paper presents corrosion protection for electrical power equipment using Cocos Nucifera leaf powder. Fourier Transform Infrared Spectroscopy (FTIR) is computed to observe chemical properties of inhibitor and the inhibitor efficiency was calculated using electrochemical measurement. The abilities of carbonyl compound in to adsorb on the surface of metal was the main reason Cocos Nucifera leaves powder to be good corrosion inhibitor. Electrochemical measurement shows that the presence of Cocos Nucifera leaves powder has ability to decreases the corrosion rates as the concentration of Cocos Nucifera leaf powder increases. Furthermore, inhibitor able to provide the best protective ability of copper from corrosion process due to the increments of polarization resistance. The results show that the efficiency of inhibitor was directly dependent on the concentration of inhibitor proved that Cocos Nucifera Leave is a good corrosion inhibitor. By further research, in future work, coating element of Cocos Nucifera leave to electrical equipment and the application of Cocos Nucifera leaves powder as green inhibitor to other metal can be accomplished.
