Abstract
- Hibiscus vitifolius was found to possess the promising potential required for reinforcing polymer matrices. In this study, Hibiscus vitifolius fibers were immersed in 2, 3, 4, 5, 6, 7, and 8% NaOH solution for 1 hr and the effects of alkali treatment on chemical, mechanical and thermal characteristics of the fiber were evaluated through chemical tests, X-ray diffraction, Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis, tensile tests, and field emission scanning electron microscopy. From the test results, it was inferred that Hibiscus vitifolius fibers treated using 5% NaOH exhibited high crystallinity, tensile strength, and Young's modulus compared to raw fibers. Beyond 5% NaOH treatment, the fibers suffered a decline in crystallinity index and mechanical properties. The morphological analysis of alkali-treated fibers revealed the removal of amorphous constituents and separation of fiber bundles into individual fiber filaments. [ABSTRACT FROM AUTHOR]
