Abstract: Bamboo is an abundant natural resource in Asia and one of the high potential fibers used to reinforce polymer composites. This article presents a comparative study on the physicochemical and thermal properties of bamboo fiber (BF) from Gigantochloa scortechinii for untreated BF, steam explosion (SE) treatment BF, and steam explosion followed by alkali (SE-alkali) treatment BF. The physicochemical and thermal properties of BF were determined using energy dispersive X-ray (EDX) spectroscopy and thermogravimetric analysis (TGA), while scanning electron microscopy (SEM) was used to examine the surfaces morphologies. A Fourier transform infrared (FTIR) spectroscopy was utilized to detect the presence of functional groups. TGA results showed that SE BF was significantly more thermally stable than the untreated BF and SEalkali treatment BF. Major changes in chemical composition and surface morphology of the bamboo fibers indicated that hemicellulose and lignin were removed by SE-alkali treatment. In conclusion, the BF surface is physically and chemically modified by the SE-alkali treatment. Keywords: Bamboo fiber, Steam explosion, Alkali treatment, Physicochemical, Thermal
polyamide 6/sugarcane bagasse composites was caused by voids and the broken fibers. The chemical structure and polarity of the fiber and matrix play an important role to enhance the adhesion [12]. Increasing the hydrophobicity of the natural fibers will result in enhanced mechanical properties and compatibility between the matrix and natural fibers [12]. Therefore, appropriate treatment should be employed to improve the adhesion between natural fibers and polymer matrices. Various types of fiber treatments or surface modifications have been performed to increase the adhesion between natural fibers and polymer matrices. These treatments include the application of silane coupling agent, alkali, permanganate, acetylation, benzoylation, and steam explosion (SE). Bamboo fiber (BF) composites prepared via SE treatment exhibited higher tensile strength compared with the same c
