This study investigates the fundamental properties of a novel plant fiber extracted from the bark of Acacia nilotica L. tree. Chemical analysis reveals its various compositions, thermogravimetric analysis determines its maximum degradation temperature, X-ray diffraction analysis calculates its crystallinity index and crystalline size, atomic force microscope evaluates its surface topography, and density measurement confirms it as a suitable material for fabricating green composites.
The present work is planned to investigate the fundamental properties of the novel plant fiber extracted from the bark of Acacia nilotica L. tree. The various chemical compositions of the Acacia nilotica L. fiber (ANF) such as cellulose (56.46 wt. %), hemicelluloses (14.14 wt. %), lignin (8.33 wt. %) and ash content (4.95 wt. %) were identified through the chemical analysis. The maximum degradation temperature of ANF (339 degrees C) was determined by the thermogravimetric analysis. The crystallinity index (44.82%) and crystalline size (3.21 nm) of the ANF were calculated by the X-ray diffraction analysis. The surface topography of ANF was estimated through the atomic force microscope. The density of ANF was identified as a value of 1165 kg/m(3) which is comparatively lower than the other renowned fibers such as Acacia leucophloea (1385 kg/m(3)) and Jute (1460 kg/m(3)); this would be confirmed with all above characterization results that is an appropriate material to fabricate the green composites.
