Abstract: | The 4,4,-oxydiphthalic anhydride-chitosan (ODAC) filler at composition of 2–12 wt/v% was selected to reinforce the Cs matrix
by solution casting method. The thermal properties of the bio-composites were then evaluated by thermogravimetry analysis,
differential scanning calorimetry, and dynamic mechanical analysis. The addition of ODAC filler in Cs matrix up to 10 wt/v%
had increased the thermal stability of the bio-composites by increasing the thermal degradation (T
d) and glass transition temperature (T
g) of the bio-composites. Good interfacial bonds of electrostatic interactions and inter-hydrogen bonds of the bio-composite
components significantly influenced the thermal properties of the bio-composites. |
