In this research article, a leftover of Cymbopogon flexuosus stem (CFS) collected from the oil extraction industry was examined for its ability as a reinforcing agent in a polymer composite. Anatomical, morphological, physical, chemical, mechanical, and thermal characteristics of the CFS fiber were examined. Chemical analysis revealed the presence of higher amount of cellulose (68.13%), which offers better bonding properties and higher tensile strength (431.19 ± 23.96 MPa). Moreover, the density of the fiber (1270 kg/m3) found using physical analysis was less than that of synthetic fibers, which paves a path in replacing hazardous synthetic fiber. Solid-state nuclear magnetic resonance and Fourier transform infrared spectrum spectroscopy analyses were conducted to study the functional groups of the extracted CFS fiber. The thermal stability (253.17°C), activation energy (73.01 kJ/mol), and maximum degradation temperature (345.08°C) were investigated by thermogravimetric analysis. X-ray diffraction analysis confirmed the semi-crystalline nature of the fiber with crystallinity index (46.02%) and crystallite size (13.96 nm). The CFS had a smooth surface, as conformed by an atomic force microscopy and scanning electron microscope analysis. Altogether, this study highlights the feasibility of leftover CFS fiber residue as reinforcement in biopolymer matrices replacing synthetic fiber.

工业废弃新型弯腰柏茎纤维的表征:合成纤维的潜在替代品

在这篇研究文章中,研究了从石油开采业收集来的弯腰柏Cymbopogon flexuosus)茎(CFS)的残余物在聚合物复合材料中作为增强剂的能力。检查了CFS纤维的解剖,形态,物理,化学,机械和热学特性。化学分析表明,纤维素含量较高(68.13%),具有更好的粘合性能和较高的拉伸强度(431.19±23.96 MPa)。此外,纤维的密度(1270 kg / m 3)发现,使用物理分析方法比合成纤维方法要少,这为替代危险的合成纤维铺平了道路。进行了固态核磁共振和傅立叶变换红外光谱分析,以研究提取的CFS纤维的官能团。通过热重分析研究了热稳定性(253.17℃),活化能(73.01 kJ / mol)和最高降解温度(345.08℃)。X射线衍射分析证实了具有结晶度指数(46.02%)和微晶尺寸(13.96nm)的纤维的半结晶性质。通过原子力显微镜和扫描电子显微镜分析,证明CFS具有光滑的表面。共,
