Novel polymeric inhibitor fo corrosion of 575 a um-nium in 2M NaOH solutions

Abstract

Purpose -The purpose of this paper is to show how to develop inhibition 575 aluminium in 2M NaOH solution. Design/methodology/approach -The approach is used to measure gravimetric and polarization measurements. Findings -The results of the paper clearly reveal that the 0.2 M ZnO with 700 ppm polyaniline in N-methyl-2-pyrrolidone solution is found to offer inhibition up to 71.2 per cent. Originality/value -The paper deals with the development of newer inhibitor based on polyaniline. Gravimetric and galvanostatic methods were employed to evaluate inhibition efficiency
