Effect of benzoylation treatment on tensile properties of sustainable bamboo species: Pseudoxytenanthera ritcheyi

This study undertakes a comprehensive exploration into the impact of chemical reagents on the distinctive bamboo species, Pseudoxytenanthera ritcheyi (P. ritcheyi). The research involves a meticulous examination of chemical characterization, encompassing subsequent chemical modification processes like alkaline treatment and benzoylation treatment applied to virgin bamboo fibers. The benzoylation treatment, preceded by alkaline pretreatment, is conducted with varying durations—10, 15, and 20 minutes. Various physical and mechanical characterization techniques are employed to assess the hydrophobic nature and strength of the fibers. Tensile properties of both treated and untreated single fibers of P. ritcheyi bamboo are measured using a computerized universal testing machine in accordance with ASTM standards. The obtained results are then compared with reference samples and commercially available natural fibers. The primary objective of this investigation is to analyze and juxtapose the axial tensile modulus and ultimate strength of P. ritcheyi bamboo fibers, employing different surface modification techniques. The thermal stability of both treated and untreated fibers is scrutinized through thermogravimetric analysis. Additionally, scanning electron microscopy (SEM) is utilized to examine the fracture morphology of the samples.
