This study information the synthesis of polypyrrole/Cr2O3 doped nanocomposites (NCs) as a shielding pigment in organic coatings. Polypyrrole/Cr2O3 doped NCs were prepared by in situ chemical oxidative polymerization of pyrrole monomer. Here dopant Cr2O3 nanoparticles (NPs) were synthesized by solution combustion method using Aloe-vera gel as fuel with ammonium per sulphate (APS) as oxidant. Different concentrations of Cr2O3 (10-50 wt %) NPs were incorporated into the polypyrrole. The synthesized nanocomposites were characterized by means of powder X-ray diffraction (PXRD) and Scanning electron microscopy (SEM). The size of the NPs were calculated by Scherer method, and found to be around 20 nm. TEM results are in consistent with the XRD results. The morphology of the obtained composites shows the porous and agglomerated particles which are due to large amount of gas evolution during NPs synthesis by solution combustion method and electrical properties were studied.
