Fibrous Cerium (IV) Hydrogen Phosphate Membrane Self-Supported Benzimidazole Polymerization Agent

Nanosized fibrous cerium phosphates, Ce (HPO 4 ) 2 .2.9H 2 O (nCeP f ), wa prepared. was characterized by chemical , XRD, TGA analysis, Scanning electron microscope (SEM) and transmission electron microscope (TEM). Novel supported polybenzimidazole/ fibrous cerium phosphate nanocomposite membrane was prepared via in-situ chemical oxidation of the monomer 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 material was characterized by XRD, TGA, elemental (C,H,N) analysis and by FT-IR spectroscopy. Image SEM of the resulting nanocomposite reveals a uniform distribution of the polymer on the inorganic matrix }. Amount of polymer present in the composites found to be 11%.
