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

Sida mysorensis 纤维的物理化学、热学和表面形态学特性（SMF）在本文中首次进行了调查。从化学成分分析来看，较高的纤维素（53.36 wt. %）和较低的半纤维素（15.23 wt. %）、木质素（9.46 wt. %）、蜡（0.86 wt. %）和（3.33 wt. %）SMF的灰分含量分别为承认。通过傅里叶变换红外光谱仪测定SMF的不同官能团。通过 X 射线衍射分析证明了 SMF 的结晶度指数 (41.17%) 和晶体尺寸 (13.06 nm)。原子力显微镜研究用于研究 SMF 的表面形态。通过热重分析确定 SMF 的热稳定性 (220°C) 和动能活化能 (65.486 KJ/mol)。所有上述发现确保了 SMF 可以用作聚合物复合材料中的增强材料。
