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.
