Abstract
A polymer is a large molecule, composed of many smaller units bonded together by covalent bond. Polymeric material may be inorganic, organic, natural or synthetic. Polymer nano composite are those materials in which nanoscopic inorganic particles typically 10-100A0 in at least one dimension are dispersed in an organic polymer matrix. This type of materials has many important properties such as linear, optical, electronic and conducting. Polymer nano composite exhibits mechanical characteristics, heat resistance and chemical resistance. Nano composite are used as advance owner material and high quality colour copiers. The polymer nano composites Ni0.3Mn0.7Fe2O4 (1), Ni0.6Mn0.4 Fe2O4 (2), Co0.3Mn0.7 Fe2O4 (3) and Co0.6Mn0.4 Fe2O4 (4) were synthesized by the ferric chloride, target metal salts and acrylic acid aqueous solution in 2:1 molar ratio under with stirring. The above compounds were characterized by IR and XRD spectral techniques. The IR spectra of oxides 1, 2, 3 and 4 appeared in the range 438-628cm-1 which shows the formation of a single phase spinal structure having two sub lattices, tetrahedral and octahedral sites. Besides that, the two peaks appear in the range of 1367 -1381 cm-1 are due C-O stretching by anhydride group in the metal oxides, confirms the acrylic acid formed as polymer with spinal oxide. The XRD powder pattern of oxides 1, 2, 3 and 4 shows a cubic crystal with unit cell dimensions and crystalline sizes in the range of 8.299-8.33A0 and 15-21nm, respectively
