Influence of chemical treatment on tensile strength, water absorption, surface morphology, and thermal analysis of areca sheath fibers

ABSTRACT

Proper surface modification is highly essential to improve compatibility of natural fibers with polymer matrix to develop eco-friendly materials. In the present work, an attempt has been made to study the effect of various chemical treatments such as alkaline, acrylic acid, permanganate, sodium chlorite, and benzoylation on areca sheath fiber. After surface modifications, its density, water absorption property, mechanical property, thermal gravimetry analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and surface morphology have been thoroughly investigated. It has been observed that benzoyl chloride-treated fiber gives better performance in comparison to other treatments.

摘要

适当的表面改性对于提高天然纤维与聚合物基体的相容性，开发环保材料至关重要。在目前的工作中，已尝试研究各种化学处理，如碱、丙烯酸、高锰酸钾、氯酸钠的作用，并对槟榔鞘纤维的苯甲酰化反应。经过表面修饰，其密度、吸水性能、力学性能、热重分析（TGA）、傅里叶变换红外光谱（FTIR），和表面形态已经被彻底的调查。已观察到，与其他处理相比，苯甲酰氯处理的纤维具有更好的性能。
