 Abstract:

The polymer nanocomposites (a) Al2O3 Fe2O4 (b)PtO2 Fe2O4 were synthesized by ferric chloride target metal salts and methyl acrylate aqueous solution 2:1 molar ratio with stirring. FTIR, X-ray diffraction (XRD) atomic force microscopy (AFM), thermogravimetric analysis (TG&DTG) and differential scanning calorimetry (DSC) were employed to character the resultant  and nanocomposites. The results of XRD and AFM showed that nanocomposite were a hybrid of polymer and metal oxides nanoparticles which were distributed uniformly in general. The FTIR spectra of oxides (a and b) appeared in the range 428-635 cm-1 which shows the format of  a single phase spinal structure having two sub lattices, tetrahedral and octahedral sites. Two peaks appear in the range of 1274-1380 cm-1 are due to C-O stretching by anhydride group in metal oxides, emphasizes the methyl acrylate formed as polymer with spinal oxide. The (TG&DTG) analysis gave an indication of the thermal dissociation nature of the inorganic Nano-composites at high temperatures. DSC characterization of Nano-composite materials showed the effect of fillers on the crystallization behavior of the pure methyl acrylate. The corrosion resistance in saline water (3.5% NaCl) at 293K where studied.
