| Summary: | The increasing global demand for sustainable materials has led to the enthusiasm for the usage of novel plant-based fibers as raw materials. This study focuses on characterizing Helicteres isora fibers to comprehend their substantial reinforcement potential in polymeric composites. The study investigates fibers derived from Helicteres isora, subjected to Alkali treatment, Methacryl silane treatment, and Potassium permanganate treatment. The investigation involves a comprehensive characterization of these fibers, including study of physical, chemical, thermal and tensile properties, aiming to understand the impact of different chemical treatments. Characterization studies encompass infrared spectroscopy and X-ray diffraction to determine changes in functional groups and crystallinity of fibers. Physical characteristics, including morphology and surface properties, are examined through techniques such as optical and scanning electron microscopy. The alkali-treated fibers exhibit 4% and 30% increase in tensile strength and modulus, respectively. Silane-treated fiber has shown an 18% reduction in water absorption compared to untreated fiber. This study provides a thorough investigation of the physical, chemical, thermal and mechanical characteristics of the untreated and chemically treated Helicteres isora fibers. The findings contribute to a deeper understanding of the potential applications of these treated natural fibers in diverse applications. |
