Electrospinning of Eucalyptus Cellulose Nano Fiber and Improving Its Properties by Doping Nano Materials

ABSTRACT

This study introduces the extraction of cellulose from eucalyptus and producing nano fibers of this cellulose which is doped with nano materials. The goal of this paper is enhancing some properties of cellulosic fiber. So, eucalyptus cellulose was extracted through a novel method and nano composite of cellulose\Ag\Cu\GeO₂ was electrospun. The FESEM images and the EDX and elemental mapping analysis indicates the excellent distribution of nano particles without aggregation and\or agglomeration. Ultra Violet blocking property of samples shows that the treated samples and doping of GeO₂ to the eucalyptus cellulose\Ag\Cu was improved. Based on the photocatalytic activity of used nano materials, the self-cleaning property of treated sample were investigated and the results showed that by adding nano GeO₂ to the eucalyptus cellulose has a tangible effect on photocatalytic activity of sample in comparison of sample with nano Ag-Cu. Furthermore, the anti-inflammatory of the samples studied on rats the result demonstrate that the produced samples can be helpful for edema reduction. Also, cytotoxicity of samples were investigated through MTT assay and cell viability of samples show low toxicity to fibroblast cell.

摘要

本文介绍了从桉树中提取纤维素，制备掺有纳米材料的纤维素纳米纤维. 本文旨在提高纤维素纤维的某些性能. 为此，采用一种新的方法提取桉树纤维素，并对纤维素-Ag\Cu\GeO2纳米复合材料进行静电纺丝. FESEM图像、EDX和元素图谱分析表明，纳米颗粒分布均匀，无团聚和/或团聚现象. 样品的紫外阻隔性能表明，处理后的样品和掺杂GeO2对桉树纤维素Ag-Cu的阻隔性能得到了改善. 以所用纳米材料的光催化活性为基础，考察了处理后样品的自清洁性能，结果表明，在桉树纤维素中加入纳米GeO2对样品的光催化活性有明显的影响. 此外，对大鼠的抗炎作用进行了研究. 结果表明，制备的样品有助于减轻水肿. MTT法检测样品的细胞毒性，细胞活力显示样品对成纤维细胞毒性较低.
