Characterization of novel natural cellulosic fiber extracted from the stem of Cissus vitiginea plant

In this study, a new natural fiber obtained from the stem of Cissus vitiginea has been studied for the first time. Chemical composition results confirmed that the proposed fiber has a rich amount of cellulose (65.43 wt%) and lower quantity of hemicellulose compounds (14.61 wt%),which in turn leads to better mechanical characteristics. Various chemical groups distributed over the fiber surface were predicted and reported with the help of Fourier transform infrared spectroscope and nuclear magnetic response spectroscopy. The crystalline nature of the fiber surface was examined using X-ray diffraction spectroscopy and the crystallinity index value was calculated to be 30.5% with 12.69 nm crystallite size. Morphological study was conducted on the fiber using a scanning electron microscope. The thermal stability of the fiber was found to be 304 degrees C with 68.72 kJ/mol kinetic activation energy. Hence C. vitiginea fiber can be suggested as reinforcement for the thermoplastic green composite. (c) 2020 Elsevier B.V. All rights reserved.
