Exfoliated Zirconium Phosphate-Fibrous Cerium Phosphate Nanocomposite Membrane Self Supported Indole, Its Co-Aniline and Co-Pyrrole Polymerization Agent

Nanosized zirconium phosphate and nano fibrous cerium phosphate, Zr(HPO4)2.H2O(nZrP), Ce(HPO4)2.2.9H2O (nCePf), respectively, were prepared and characterized. Mixing slurry aqueous solution of (nZrP and nCePf) in 25:75 wt/wt% mixing ratios), respectively, lead to formation of novel zirconium phosphate- fibrous cerium phosphate nanocomposite membrane, (Zr(HPO4)2)0.25(Ce(HPO4)2)0.75.3.87H2O(nZrP-nCePf), and was characterized. Zirconium phosphate-fibrous cerium phosphate / polyindole, - / polyindole-co-polyaniline and -/polyindole-co-polypyrrole nanocompsite membranes were prepared via in-situ chemical oxidation of the indole, and its co-monomers, that was promoted by the reduction of Ce(iv) ions present in the inorganic matrix of (nZrP-nCePf ) nanocomposite membrane. A possible explanation is nCePf present on the surface of the fiber is attacked by indole and its co-monomers, converted to cerium (III) orthophosphate(CePO4). The resultant materials were characterized by elemental (C,H,N) analysis, FT-IR, and scanning electron microscopy(SEM). The rest nanocomposite membranes morphology was preserved. SEM images of the resulting nanocomposites reveal a uniform distribution of the polymer and co-polymers on the inorganic matrix. From elemental (C,H,N) analysis the amount of organic material present in (nZrP-nCePf)/PIn composite found to be (8.83% in wt.). Where the amount of organic material present in (nZrP-nCePf)/PIn-co-PANI found to be PIn =17.51, PANI = 26.26% in wt., and for (nZrP-CePf) / PIn-co-PPy found to be PIn = 21.84, PPy = 29.13 % in wt..
