Study the Structure, Morphology, and Thermal Behavior of Banana Fiber and Its Charcoal Derivative from Selected Banana Varieties

ABSTRACT

The structure, the morphology and the thermal behavior of fibers extracted from common banana varieties (‘Ambun’ (Cavendish AAA), ‘Ambul’ (Mysore AAB), ‘Kolikuttu’ (Silk AAB), ‘Seenikesel’ (Pisang Awak ABB),’ Alukesel’ (ABB) found in Sri Lanka have been investigated using XRD, FTIR, SEM, and DSC. All the samples exhibited similar X-ray diffraction patterns, FTIR spectrums and DSC thermograms. SEM analysis revealed the presence of rough surface with filaments in all five banana varieties and detailed analysis revealed that there is a hollow structure in the aforesaid fiber varieties. Considering the similarity of the different fibers, the possibility of using a mixture of banana fiber varieties to prepare economical banana fiber charcoal was also investigated. Prepared charcoal was also characterized using XRD, FTIR & SEM. It was observed that the charcoal prepared from two or five different banana varieties showed similar X-ray diffraction patterns, FTIR spectra as well as similar morphology. Since the properties of banana fiber as well as the banana charcoal are irrespective to the banana variety used to prepare them, the collection and the manipulation of the banana waste becomes facile in commercial application.

香蕉纤维的结构、形态和热性能及所选品种的炭衍生物的研究

在斯里兰卡已经利用XRD，FTIR、SEM、DSC对普通的香蕉品种 (‘Ambun’ (Cavendish AAA), ‘Ambul’ (Mysore AAB),‘Kolikuttu’ (Silk AAB), ‘Seenikesel’ (Pisang Awak ABB),’ Alukesel’ (ABB) 中提取的纤维的结构，形态，热性能进行了研究。所有的样品表现出类似的X射线衍射、红外光谱、DSC热分析图。扫描电镜分析表明，在所有五个香蕉品种中，存在粗糙的表面，并进行了详细的分析，结果表明上述纤维品种有一个中空结构。考虑到不同的纤维的相似性，混合香蕉品种纤维的制备经济香蕉纤维木炭的可能性。利用X射线衍射仪、红外光谱和扫描电镜对所制备的炭进行了表征观察。观察到，从两个或五个不同的香蕉品种制备的炭表现出类似的X-射线衍射图案，红外光谱以及类似的形态。由于香蕉纤维以及香蕉的炭衍生物跟香蕉品种无关的特性，在商业应用中，香蕉废物的收集和操作变得简便。
