Morphological, Physical, and Thermal Properties of Chemically Treated Banana Fiber

摘要

环境意识和提高绿色技术的认识已经激起了行业的整个走向新的 材料,而不是使用合成聚合物纤维.天然纤维可以是一个很好的替代品为他们提供低成本的纤维形成.在这项研究中,在60℃, 使用次氯酸钠NaC10 /水(1:1),香蕉的化学处理纤维(穆萨 sapientum)进行了讨论.化学处理的目的是提高纤维基体的相容 性,界面强度,物理,和热性能等,在处理纤维的化学组成控制 纤维素含量的增加和减少的非纤维素类材料.化学处理的变 化,通过傅立叶变换红外光谱和X-射线衍射方法分析.扫描型电 子显微镜研究显示经化学处理后的表面形貌的变化.而且,处理 后的纤维表现为减少水的吸收和更好的热性能.%Environmental consciousness and increasing awareness of green technology have stirred the entire gamut of industry to move toward new materials instead of using synthetic polymeric fibers. Natural fiber can be a good substitute as they are available in fibrous form at low cost. In this study, the chemical treatment of banana fiber (Musa sapientum) using sodium hypochlorite NaClO/H_2O (1:1) at 60PC is discussed. The purpose of chemical treatment is to improve the fiber-matrix compatibility, interfacial strength, physical, and thermal properties, etc. The chemical composition of fibers on treatment indicated increase of cellulose content and decrease of noncellulosic material. The changes due to chemical treatment were analyzed by Fourier transform infrared and X-ray diffraction methods. Scanning electron microscope studies revealed the changes in surface morphology after chemical treatment. And also, the treated fibers showed reduced water uptake and improved thermal properties.
