Abstract
Composites of polyaniline with calcium carbonate particles (PANI/CaCO3) withdifferent CaCO3 content (0-40 %w/w) were prepared. Two different methods of in situpolymerization and solution mixing were used for PANI/CaCO3 composite preparation.The composite was characterized using FT-IR, SEM, electrical conductivitymeasurement and cyclic voltammetry techniques. The incorporation of CaCO3 particlesin polyaniline matrix in both methods of composite preparation was confirmed by FTIR results. Electrical conductivity measurements showed that the conductivity of thecomposite decreases by increasing the CaCO3 loading in polyaniline. Also, theanticorrosive property of the PANI/CaCO3 composite coating on iron samples wasinvestigated in various corrosive environments. According to the results, the corrosionrate or corrosion current of PANI/CaCO3 composite coated iron coupons was muchlower (96.75%) than polyaniline coated samples. Also, results showed that thecorrosion current of composite coated samples varies with the variation of the CaCO3content in composite coating, and the optimum CaCO3 content of composite coating toachieve the best anticorrosive performance on iron is 10 %w/w.
