Comprehensive characterization sea purslane (Sesuvium portulacastrum) fiber and the effect of surface modifications on physical, mechanical and thermal properties

ABSTRACT

In the present work, a novel purslane (Sesuvium portulacastrum) fiber has been identified and the effect of surface modifications on its physical, mechanical, and thermal properties has been studied. The fiber surface has been treated with different chemicals, such as sodium hydroxide, acrylic acid, maleic anhydride, potassium permanganate, and benzoyl peroxide. The density, water absorption property, mechanical properties, thermogravimetry analysis, Fourier transform infrared spectroscopy, and surface morphology have been thoroughly investigated. It has been observed that acrylic-acid-treated purslane fiber gives better performance in comparison to other treatments with an enhancement of 36.68% of tensile strength as compared to untreated fibers.

摘要

本文对一种新型的马齿苋（Sesuvium portulacastrum）纤维进行了鉴定，并研究了表面改性对其物理、力学和热性能的影响. 纤维表面用氢氧化钠、丙烯酸、马来酸酐、高锰酸钾和过氧化苯甲酰等不同的化学物质进行了处理. 对其密度、吸水性能、力学性能、热重分析（TGA）、傅立叶变换红外光谱（FTIR）和表面形貌进行了深入研究. 结果表明，经丙烯酸处理的马齿苋纤维的拉伸强度比未经丙烯酸处理的纤维提高了36.68%.
