| dc.description.abstract | The interfacial bonds, homogeneity and rigidity of filler are the two main criteria that significantly influenced the mechanical, thermal and hydrophilicity of the chitosan (Cs) based bio-composites. Therefore, the aim of this study was to investigate the role of cross linked chitosan (XCs) as filler in the Cs matrix towards the interfacial, homogeneity and rigidity of the produced Cs bio-composites. XCs was synthesized using three different cross linking agents named as 1,2,4,5-benzentetra carboxylic (BT), 4,4’-oxydiphtalic anhydride (ODA) and 3,3’,4,4’-diphthalic anhydride (DPA) which consequently produced three different types of XCs filler; 1,2,4,5-benzentetra carboxylic-chitosan (BTC), 4,4’-oxydiphtalic anhydride-chitosan (ODAC) and 3,3’,4,4’- diphthalic anhydride-chitosan (DPAC). The formation amide structure (as the cross linking bridge) was chemically, physically and thermally prove via the Fourier Transform Infra-Red (FTIR), 1H and 12C Nuclear Magnetic Resonance (1H and 12CNMR), elemental analysis, Energy Dispersive X-ray Spectroscopy (EDXS), X-ray diffraction (XRD), particle size analysis, density, Thermogravimetry (TG), Differential Scanning Calorimetry (DSC), Field Emission Scanning Electron Microscope (FESEM), solubility and swelling analysis. The solution casting technique was used to fabricate the Cs/XCs bio-composites with the filler content of 0 to 12 wt/v %. The properties of the produced bio-composites were analyzed on its mechanical (under tensile and tearing testing), thermal (TG, DSC and Dynamic Mechanical (DM) analysis) and hyrophilicity properties (under swollen medium of pH 2 to 12). | en_US |
