Preparation and Anticorrosion Properties of PANI/Coal Composites Material
摘要
Abstract
The PANI/Coal nanocomposites were synthesized by still-setting method with aniline mono-mer and coal.The composites were added in epoxy and then coated on megnesium alloy coupons.After curing,the PANI/Coal/epoxy anticorroion coatings were obtained.The structure,morphology and properties of samples were characterized by Fourier transformation infrared (FTIR)spectroscopy,scan-ning electron microscopy (SEM),and electrochemical impedance spectroscopy (EIS)in 3.5% NaCl so-lution.The results show the acid doped PANI/Coal composites have been synthesized,and the samples exist as nanorods structure.The corrosion current density and corrosion rate of PANI/Coal composites coatings decrease 2~3 orders compared with pure magnesium alloy.The impedance at low frequency of coatings enhances with the increasing PANI/Coal composites.When the PANI/Coal composites is 20%, the corrosion resistance reaches a best point and with a slow change rate.The anticorrosion properties decrease with the immersion time in 3.5% NaCl solution.The samples with 15% PANI/Coal compos-ites exhibit optimum anticorrsion behaviour.关键词
