Polymer hybrids have become a major area of research and development owing to the remarkable properties and multifunctional behaviour deriving from their nanocomposite/nanohybrid structure. In this class, magnetic polymer nanocomposite are of special interest because of the combination of excellent magnetic properties, high specific area, surface active sites, high chemical stability and good biocompatibility. The present communication primarily concentrates on the investigation of structural characterization of alginate–cobalt ferrite nanocomposite (CoFe2O4–ANa NC) prepared by ex situ polymerization method. The structural and morphological properties of CoFe2O4–ANa NC were analysed using X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and dynamic light scattering. The specific surface area of the nanocomposite was analysed using BET surface area analysis. The functional group and the thermal stability were examined using FTIR and TGA/DTA respectively. The characterization results have pointed out the successful role of sodium alginate in stabilizing cobalt ferrite nanoparticles (CoFe2O4 NP). The SEM and TEM images revealed the well interspersed state of cobalt ferrite with sodium alginate. It is obvious to note the increased size and the specific surface area for CoFe2O4 nanocomposite.
