Nano Fibrous Cerium (IV) Hydrogen Phosphate Membrane Self Supported Aniline Polymerization Agent

TL;DRAbstract

Nanosized fibrous cerium (iv) Hydrogen phosphate membrane, Ce(HPO4)22.9H2O (nCePf), was prepared and characterized. Novel supported nanofibrous cerium phosphate / polyanaline nanocomposite membranes were prepared via in-situ chemical oxidation of the monomer aniline, that was promoted by the reduction of Ce(iv) ions present in the inorganic matrix. The presence of Ce (iv) ions allows redox reactions necessary to oxidative polymerization to occur. The resultant materials were characterized by TGA, elemental (C, H, N, S) analysis and FT-IR spectroscopy. Images SEM of the resulting nanocomposites reveal a uniform distribution of the polymer on the inorganic matrix. A possible explanation is nCePf present on the surface of the fiber is attacked by the aniline and converted to cerium(III) orthophosphate (CePO4). The rest of the (nCePf) was preserved. The degree of polymer loading and its type can be controlled by varying method of the preparation. Accordingly two types of green emeraldine s
