Abstract

Nanosized fibrous cerium phosphates, Ce(HPO₄)₂.2.9H₂O (nCeP_f), was prepared and characterized. Poly (vinylalcohol)/fibrous cerium phosphate nanocomposite membranes of different weight percentages (2.5,5,10 and 20 wt %) were synthesized. and found to be transparent flexible thin films. They were characterized by chemical, XRD, TGA analysis, and transmission electron microscopy (TEM). TEM images of PVA/nCeP_f nanocomposites show fibrous cerium phosphate in the nanometer scale, in the range of 12-15 nm, and was dispersed in the PVA matrix. The composite materials show to have mechanical and thermal stability properties superior to that of the original polymer. The exchange capacities of composite membranes were investigated and found to be equivalent to summation of ion exchange capacities of PVA and the inorganic filler (nCeP_f) wt % loading.
