Suitability Evaluation of Sida mysorensis Plant Fiber as Reinforcement in Polymer Composite

ABSTRACT

The physicochemical, thermal, and surface morphological properties of the Sida mysorensis fiber (SMF) were investigated first time in this article. From the chemical compositional analysis, higher cellulose (53.36 wt. %) and lower hemicelluloses (15.23 wt. %), lignin (9.46 wt. %), wax (0.86 wt), and ash content of (3.33 wt. %) SMF were acknowledged. The different functional groups of SMF were determined through the Fourier transform infrared spectrometer. The Crystallinity index (41.17%) and crystalline size (13.06 nm) of SMF were evidenced through the X-ray diffraction analysis. Atomic force microscopy investigation was used to study the surface morphology of SMF. Thermal stability (220°C) and kinetic activation energy (65.486 KJ/mol) of the SMF were determined through the thermogravimetric analysis. All the above findings ensured that SMF can be used as reinforcement in polymer composite.

摘要

本文首次研究了Sida mysorensis纤维（SMF）的理化、热学和表面形态特性. 化学成分分析表明，SMF的纤维素含量较高（53.36%），半纤维素含量较低（15.23%），木质素（9.46%），蜡（0.86 wt.）和灰分（3.33 wt.%）. 利用傅立叶变换红外光谱法测定了不同官能团的表面活性剂. 通过X射线衍射分析，确定了SMF的结晶度指数（41.17%）和晶粒度（13.06nm）. 采用原子力显微镜对表面形貌进行了研究. 通过热重分析测定了SMF的热稳定性（220oC）和活化能（65.486kJ/mol）. 以上研究结果表明，SMF可以作为聚合物复合材料的增强体.
