Cellulose nanofibers isolation and characterization from ramie using a chemical-ultrasonic treatment

ABSTRACT

The novelty of this work lies in isolating cellulose nanofibers from ramie (Boehmerianivea (L.) Gaud) using chemical-ultrasonication treatment. The cellulose nanofibers were successfully isolated from ramie with a diameter and length of 9.9–89.1 nm and 1 μm, respectively. The samples were characterized by scanning electron microscopy, transmission electron microscopy, particle size analysis, Fourier transform infrared spectroscopy, X-ray diffraction analysis, and thermogravimetric analysis. Indeed, there is a decrease in the hemicellulose and lignin content while the cellulose content increases due to the pulping and bleaching processes. The chemical-ultrasonication treatment results in a high yield of cellulose nanofibers (89.35%).

摘要

本文的新颖之处在于从苎麻中分离纤维素纳米纤维（Boehmerianivea（L.）Gaud）使用化学超可听化处理。分别从直径为9.9～89.1 nm和1μm的苎麻中分离出纤维素纳米纤维。通过扫描电镜、透射电镜、粒度分析、傅立叶变换红外光谱、X射线衍射分析、热重分析等手段对样品进行了表征。事实上，半纤维素和木质素含量减少，而纤维素含量的增加由于制浆和漂白过程。在高产量的纤维素纳米纤维化学超声治疗结果（89.35%）。
