Extraction and Characterization of Nano-cellulose Fibrils from Indian Sugarcane Bagasse- an Agro Waste

& ORCID Icon
 

ABSTRACT

India is among the largest producers of sugarcane in the world. Sugarcane bagasse (SCB) has been used in different applications in the area of sugar and its products, biomedical sciences, biotechnology, textile industry, etc., and its utilization as a source of cellulose is also gaining rapid popularity in construction and health sector. The aim of the study is to analyze the surface morphology, structure, elemental composition of sugarcane bagasse as agro-waste cellulose nano fibrils (CNFs) extracted by alkali treatment, followed by steam explosion and acid treatment. It was observed that the properties are dissimilar for each of the samples tested at each of the four different stages of chemical treatment of sugarcane fibers studied by Scanning electron microscopy (SEM), structural spectroscopy (FTIR), X-ray diffraction (XRD), and elemental analysis (energy dispersive x-ray diffraction (EDX). Based on the characterization some probable applications in fiber reinforced composites have been discussed.

摘要

印度是世界上最大的甘蔗生产国之一. 甘蔗渣在制糖及其制品、生物医学、生物技术、纺织工业等领域有着广泛的应用,作为纤维素来源的甘蔗渣在建筑和卫生领域也得到了迅速的普及. 研究了碱处理、蒸汽爆破和酸处理提取的甘蔗渣作为农业废弃物纤维素纳米纤维(CNFs)的表面形态、结构和元素组成. 通过扫描电子显微镜(SEM)、结构光谱(FTIR)、X射线衍射(XRD)和元素分析(能量色散X射线衍射(EDX))研究发现,在甘蔗纤维化学处理的四个不同阶段,每个样品的性能都不相同. 在此基础上,讨论了其在纤维增强复合材料中的应用前景.
