Abstract
In this work, CMC was synthesized from cellulose obtained from coir fibres. The obtained CMC yield was about 64.0%. The Degree of Substitution value obtained was 0.44. The spectral pattern and thermogravimetric analysis of the synthesized CMC and cellulose were evaluated using FT-IR, XRD, and TGA/DTG. Characterization of the cellulose and CMC revealed their high crystallinity with cellulose showing a lower crystallinity value due to its lignin content. The CMC also showed a higher degree of crystallinity (56.93%) and hydrogen bonding compared to some earlier literature reports for CMC. The DTG curve revealed that the CMC had a maximum rate of degradation at about 310 °C. The FT-IR spectra of the obtained CMC showed a finger print region characteristic of CMC (1590 cm-1). This work shows that the spectral characteristic and crystallinity of CMC can be related to the synthetic method applied in obtaining the cellulose prior to CMC synthesis.
