PREPARATION AND CHARACTERIZATION OF CELLULOSE FILMS FROM FICUS NATALENSIS BARK CLOTH FIBERS
Keywords:
Biodegradable, Cellulose film, Ficus Natalensis, BarkclothAbstract
In this study, cellulose films were prepared from Ficus natalensis bark cloth fibers via phase inversion technique using NaOH/urea/water as the solvent. Films were formed at a concentration of 7 wt. % and 8 wt. % of microcrystalline cellulose (MCC) as isolated from Ficus natalensis bark cloth fibers. Their morphology, physiochemical, and mechanical properties were examined with scanning electron microscopy (SEM), Fourier transform IR spectroscopy (FTIR), x-ray diffraction (XRD), thermal gravimetric analysis (TGA) and microcontrolled electronic universal testing machine. The resultant regenerated cellulose (RC) films exhibited rough surfaces morphologically, good tensile strength (19.85 ± 0.13 MPa), exhibited a plastic behavior with considerable strains. However, they are thermally stable at higher temperatures up to 280 °C. Cellulose films from this study could potentially act as biodegradable packaging materials to upgrade the scope of application of Ficus natalensis bark
