چکیده

The preparations and characterization of polypyrrole – polyethylene glycol (PPy-PEG) films are reported in this paper. The composite films were synthesized by electrochemical method in 0.2 mol·L-1 Py and 5% PEG in 0.2 mol·L-1 oxalic acid. The electrochemical behaviour of PPy and PPy-PEG coatings has been investigated in phosphate buffer solution (PBS) by cyclic voltammetry, Tafel plots and electrochemical impedance spectroscopy. The surface topography and the roughness were checked by atomic force microscopy.

Synthesis of Polypyrrole/CeO2 Nanocomposite and its Application for Improving the Corrosion Protection of Acrylic Waterborne Coating on Mild Steel

In this work, polypyrrole/CeO2 nanocomposite (NC) was synthesized in the presence of methylorange as a reactive self-degraded soft template. The field emission scanning electron microscopy(FESEM) images indicate that the CeO2 NPs have a nucleus effect and cause a homogenous PPycore–shell type morphology with an encapsulation of the CeO2 core by the PPy shell. The effect ofNC on acrylic waterbor...
