Abstract
Crystalline cerium (iv) hydrogen phosphate Ce(HPO4)2.1.33H2O(CeP), and nano particles zirconium oxide(nZrO2), of average size19.3nm, were prepared and characterized by chemical , XRD, FT-IR and TGA analysis. Mixing slurry aqueous solution of nZrO2 and CeP in 25:75 wt/wt% mixing ratios, respectively, lead to formation of novel zirconium oxide-crystalline cerium phosphate nanocomposite, [ZrO2]0.25[Ce(HPO4)2]0.75.1.33H2O(nZrO2-CeP). Novel[nZrO2]0.25[CeP]0.75/ polybenzimidazole-, polyaniline-, polyindole-, and polycarbazole nanocomposites were prepared via in-situ chemical oxidation of their parent monomers. A possible explanation is part of CeP, in inorganic composite (nZrO2-CeP) was attacked by the parent monomers converted to cerium(III) orthophosphate(CePO4). The resultant nanocomposites were characterized by elemental (C,H,N) analysis , FT-IR, and scanning electron microscopy(SEM). From elemental (C,H,N) analysis. the amount of % in wt. of organic materials present in (nZrO2-CeP) nanocomposites found to be , for [polybenzimidazole(12..56%). polyaniline (16.50%) , polyindole (11.74 %), and polycarbazole (13.99 %)]. Electrical conductivity for resultant conducting polymers were investigated using DMSO solvent found to be in the range of semiconductors.
