Abstract
This study is an attempt to establish a novel technique for the synthesis of Chitosan (CS)—Polystyrene (PS) blends to achieve specific combination of physical properties. The CS–PS blends were synthesized from homogenous solutions at different ratios of the polymers. An attempt is made to improve their functionality by doping them with mixed metal oxide nanocomposites of ZnO–TiO2 synthesized by an electrochemical thermal technique. The obtained nanocomposite doped polymer blends are appropriately characterized by Fourier Transform Infrared Spectroscopy (FT-IR) to confirm functional groups. It indicates the formation of blends due to intermolecular hydrogen bonding between the 2 components. SEM images substantiate the presence of nanoparticles in the blends. Thermal stability of these polymers is analyzed by Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). X-ray diffraction (XRD) analysis confirms the amorphous nature of the synthesized blends. These studies reveal that the obtained blends could have potential physiochemical applications as adsorbents for dyes in the treatment of effluent water from textile industries.
