Investigation of Physico Chemical Properties and Characterization of New Natural Cellulosic Fibers from the Bark of Ficus Racemosa

ABSTRACT

The objective of this examination is to characterize the fibers from the bark of Ficus racemosa fibers (FRF). FRF is composed of cellulose (72.36 wt. %), hemicellulose (11.21wt. %), lignin (10.45 wt. %), and has a density of 895 Kg/m³. The Differential thermogravimetry (DTG) shows that the maximum degradation peak temperature was attained at 310.56°C. The presence of a chemical group in the fibers was revealed through Fourier transform (FT-IR) analysis. The crystalline structure was characterized by X-ray diffraction (XRD). For surface morphology, Scanning electron microscopy (SEM) and Atomic force microscopy (AFM) were used. The obtained results indicated that FRFs are suitable fibers for polymer composite as reinforcement.

摘要

本试验的目的是对无花果树皮纤维进行定性分析. FRF由纤维素（72.36 wt.%）、半纤维素（11.21 wt.%）、木质素（10.45 wt.%）组成，密度为895 kg/m3. 差热重分析（DTG）表明，在310.56°C时，降解峰温度达到最大值. 傅立叶变换（FT-IR）分析表明纤维中存在化学基团. 用X射线衍射（XRD）对晶体结构进行了表征. 表面形貌采用扫描电子显微镜（SEM）和原子力显微镜（AFM）. 结果表明，FRF是一种适用于高分子复合材料增强的纤维.
