Kinetics of the mild steel corrosion protection by polypyrrole-oxalate coating in sulfuric acid solution

Polyaniline based corrosion inhibitors for conventional organic coatings

“…These unique features are widely considered in broad field of applications including electrochemical energy storage and conversion [9,10], magnetic shielding [11,[7][8][9][10][11][12][13][14][15][16][17][18], biosensors and sensors [14,16,17], electronic devices [18,19] and corrosion protection [20][21][22][23][24][25][26][27][28][29][30].…”

Corrosion protection of cold-rolled steel with alkyd paint coatings composited with submicron-structure types polypyrrole-modified nano-size alumina and carbon nanotubes

“…Corrosion inhibition by free-standing polypyrrole (PPy) was studied on iron [1,2] and mild steel [3]. Besides the epoxy topcoated PPy films [4], protection function of the epoxy composited coatings was investigated at PPy contents of 2-10 wt.% without statement of average size of the incorporated particles [5].…”

Corrosion protection of stainless steel by separate polypyrrole electrode in acid solutions

“…Grgur et al [18] investigated the corrosion of mild steel covered by 1.8 mm PPy layer in sulfuric acid solution using EIS, cyclic voltammetry, polarization, and linear polarization. Their results indicated that after immersion, the coating resistance parameters initially increased, probably due to the diffusion controlled dedoping of oxalate anions.…”
