Özet
Firstly, chitin was modified via ring-opening reaction with maleic anhydride in lithium chloride/
N,N-dimethylacetamide. Then, both chitin and chitin modified with maleic anhydride (CMA) were
characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) method,
ultraviolet-visible (UV-Vis) spectroscopy, and scanning electron microscopy (SEM).
Thermogravimetric analysis (TGA) was performed to investigate the thermal stability of chitin and
CMA. TGA results showed that chitin is thermally more stable than CMA. In addition, the electrical
conductivity of chitin and CMA was also measured. Electrical conductivity measurement results showed
that the electrical conductivity of CMA (4.3x10-4 S cm-1) is more than that of chitin (6.5 x 10-6 S cm-1).
