WATER-SOLUBLE POLYANILINE INHIBITOR FOR CARBON STEEL

The inhibitive effect of water-soluble polyaniline on carbon steel was investigated by weight lost when immered in 5% HCl.The best adding ratio of water-soluble polyaniline was obtained by testing the change of inhibition with adding ratio.And the effect of temperature on inhibition was also tested.The results of testing indicated that the best adding ratio of water-soluble polyaniline in 5% HCl was 0.4%,and its inhibition did not change with temperature.
