| Popis: | Synthetic nanotechnology has attracted a great deal of attention from researchers for the synthesis of assorted materials at nanoscale dimension. Researchers are more attracted to microwave-assisted route for the synthesis of ferrite nanomaterials due to its simplicity. Barium ferrite (BF) nanomaterials are prepared by two strategies: the barium oxalate and the iron oxalate strategy. Thermal decomposition of barium oxalate precursor and ferrous oxalate precursor has been done using polyvinyl alcohol (PVA) as a fuel. Self-propagating combustion reaction of metal oxalates takes place with fuel, which controls the size of the particle. Solvent casting method is used for the preparation of barium ferrite-dispersed poly(methyl methacrylate) (BF–PMMA) nanocomposite. The structure of the as-prepared samples was carried out by X-ray diffraction (XRD) study and particle morphology of the sample done by scanning electron micrograph (SEM) technique. The presence of barium and iron metals in the sample is confirmed by EDX analysis. Bonding nature of the ferrite is studied by Fourier transform (FT-IR) tool. Thermal and electrical studies of the samples are also undertaken to know the thermal electrical behaviour. UV absorbance study of the said composite is also undertaken. |
