Electrospinning of Lignocellulose Nanofibers from Dissolved Jute

ABSTRACT

Regenerating jute into high-tech nanofibers is an alternative way to use jute fibers. In this work, trifluoro acetic acid (TFA) was used as a solvent to dissolve jute fibers for fabricating nanofibers via electrospinning. Nanofibers from raw jute (JNFs) and treated jute fibers (TJNFs) were successfully fabricated from a needle-based electrospinning unit, and electrospinning parameters, such as polymer concentration, flow rate, and applied voltage, were investigated. The morphology of the electrospun JNFs and TJNFs was characterized by scanning electron microscopy (SEM) and their chemical structure by Fourier Transform Infrared (FTIR) analysis. To understand the thermal stability and decomposition behavior, thermogravimetric analysis (TGA) of the electrospun nanofibers was performed. SEM analysis showed there are no significant difference in surface morphology between JNFs and TJNFs. The TGA results confirmed that the as-spun nanofibers have excellent thermal stability which makes them less prone to degradation. This work provides insights into converting jute fibers into high-performance nanofibers.

摘要

将黄麻再生为高科技纳米纤维是黄麻纤维的一种替代方法. 本文以三氟乙酸（TFA）为溶剂，将黄麻纤维溶解，通过静电纺丝法制备纳米纤维. 采用针状静电纺丝装置成功地制备了黄麻原纤维（JNFs）和黄麻处理纤维（TJNFs）纳米纤维，并对静电纺丝工艺参数（聚合物浓度、外加电压和流速）进行了研究. 用扫描电子显微镜（SEM）表征了电纺JNFs和TJNFs的形貌，用傅立叶变换红外光谱（FTIR）分析了其化学结构. 为了确定电纺纳米纤维的热稳定性和分解模式，对电纺纳米纤维进行了热重分析. SEM分析表明，JNFs与TJNFs的表面形貌无明显差异. TGA结果表明，纺丝态纳米纤维具有良好的热稳定性，不易降解. 这项工作提供了将黄麻纤维转化为高性能纳米纤维的见解.
