Study of Natural Cellulose Fiber’s Characters in Holoptelea integrifolia Tree Bark

ABSTRACT

Natural fibers removed from the bark of Holoptelea integrifolia were characterized by chemical testing, FTIR spectroscopy, XRD, thermal analysis, and FESEM and EDAX morphological analysis. The results of chemical analysis show 65.30% cellulose, 1.36 g/cc density, and 14.69% moisture content. The results of XRD studies show 37.42% crystallinity index and 5.48 nm crystallinity size of the tested samples. Thermal studies show that after 235°C, fiber degradation occurs. SEM results prove the existence of cellulose fibrils and accumulation of polysaccharides over the fiber surface. EDAX shows an O/C ratio of 0.5419. The above results prove that Holoptelea integrifolia can be utilized as a promising reinforcement in polymers for making weightless components.

摘要

通过化学测试、FTIR光谱、XRD、热分析、FESEM和EDAX形态分析对从整叶合欢树皮中提取的天然纤维进行了表征. 化学分析结果表明. 纤维素含量为65.30%, 密度为1.36 g/cc, 含水量为14.69%. XRD研究结果表明, 测试样品的结晶指数为37.42%, 结晶尺寸为5.48 nm. 热研究表明, 235°C后, 纤维发生降解. 扫描电镜结果证明了纤维素原纤维的存在和多糖在纤维表面的积累. EDAX显示O/C比为0.5419. 上述结果证明, 整叶合欢可以作为聚合物中有前途的增强材料, 用于制造失重组件.
