Effectiveness of alkaline and hydrothermal treatments on cellulosic fibers extracted from the Moroccan Pennisetum Alopecuroides plant: Chemical and morphological characterization

This work aims to study the physical, chemical, and thermal properties of natural fibers extracted from Pennisetum alopecuroides plant. The was carried out on raw treated assess improvements that facilitate future uses in composites. alkaline treatment using NaOH with different concentrations (1, 3, 5, 10%) for 2 hours. Hydrothermal performed at immersion times a water bath 100°C. chemical composition fibers, such as cellulose, hemicellulose, lignin, ash contents, evaluated. structure fiber analyzed by FTIR, SEM, X-ray diffraction. Thermogravimetric analysis (TGA) is used stability fiber. density also investigated pycnometric methode. results showed concentration 3% during 2h most suitable solution treat P.alopecuroides fiber, but hydrothermal 1h 100°C effective this seem viable be reinforcement composites production, namely achieve goals energy efficiency.
