ABSTRACT
The ecological conservation in the current global scenario has led scholars to use natural fibers as a reinforcement in composites that resulted in the exploration of new natural cellulose fibers. This research investigates the extraction and characterization of natural cellulose fibers from the stems of Buxus sempervirens (BS) plants, which are used to produce various products. Manual retting of stems resulted in Buxus sempervirens fibers production, which was then evaluated for their physical, chemical, thermal, crystallographic, and morphological characteristics. The results elucidated that BS fibers had a cellulose percentage of 51.78%, 18.42% hemicellulose, and 17.36% lignin. The Fourier Transform Infrared Spectroscopy results validated the chemical constituents. Crystallographic investigations utilizing X-Ray diffraction revealed a crystalline index of 18.05%. The thermogravimetric analysis of BS fibers showed char residue of 33% and a maximum degradation temperature of 263°C. The BS fibers revealed good surface interlocks that can be inferred from Scanning Electron Microscope. Thus, from the results compared with other natural fibers, we demonstrate that Buxus sempervirens fibers can be effectively used as reinforcement in polymeric composites.
摘要
当前全球环境下的生态保护促使学者们将天然纤维用作复合材料的增强材料, 从而探索出新的天然纤维素纤维. 本研究调查了从用于生产各种产品的黄杨 (Buxus sempervirens) 植物茎中提取天然纤维素纤维并对其进行表征. 人工脱胶茎导致黄杨纤维的生产, 然后对其物理、化学、热、结晶和形态特征进行评估. 结果表明, BS纤维的纤维素含量分别为51.78%、18.42%和17.36%. 傅立叶变换红外光谱结果验证了化学成分. 利用X射线衍射进行的晶体学研究表明, 结晶指数为18.05%. BS纤维的热重分析表明, 残炭率为33%, 最大降解温度为263°C. 从扫描电镜可以看出, BS纤维具有良好的表面互锁性. 因此, 与其他天然纤维的比较结果表明, 黄杨纤维可以有效地用作聚合物复合材料的增强材料.
