Effect of Alkalization on Physical, Chemical, Morphological and Mechanical Properties of Arial Root Ficus Amplissima Fibre

ABSTRACT

Natural fiber’s hydrophilic property leads to reduced bond strength for its incompatibility with the matrix. This problem can be sorted out by treating the surface of the fiber. In this connection, the chemical, physical, thermal, and surface morphological properties of alkali-treated Arial root Ficus Amplissima fiber (ARFAF) have been investigated. By using the TGA, the alkali treatment of ARFAF was optimized, and 5% (w/v) NaOH and 45 min of the soaking period was found to be the best. Optimally treated ARFAF improved the cellulose content from (52.64 wt. %) to (61.67 wt. %) and reduced the hemicellulose from (10.64 wt. %) to (6.22 wt. %), crystallinity index improved from (39%) to (43.33%), tensile strength improved from (250.7 ± 11.26MPa) to (278.4 ± 13.20 MPa), thermal stability improved from (200°C) to (230°C), and it improved the surface topography compared with raw ARFAF.

摘要

天然纤维的亲水性导致其与基体的不相容性导致粘结强度降低. 这个问题可以通过处理纤维表面来解决。在这方面,研究了碱处理的Arial根榕纤维(ARFAF)的化学、物理、热和表面形态特性. 通过TGA对ARFAF的碱处理进行了优化,发现5%(w/v)NaOH和45min的浸泡时间是最佳的. 经过优化处理的ARFAF将纤维素含量从(52.64 wt.%)提高到(61.67 wt.%),半纤维素含量从(10.64 wt.%)降低到(6.22 wt.%),结晶指数从(39%)提高到(43.33%),拉伸强度从(250.7 ± 11.26MPa)提高到(278.4 ± 13.20 MPa),热稳定性从提高(200 C) 至(230 C) 与原始ARFAF相比,它改善了表面形貌.
