Extraction and characterization of biofiber from the Phoenix sylvestris leaf sheath biowaste for probable reinforcement in polymer composites

In order to solve sustainability issues with its processes and products, the composites sector is concentrating on bio-waste as a different origin of materials for manufacture. The properties of Phoenix sylvestris leaf sheath fiber (PSLSF), a unique agro-waste that is separated from the tree's leaf sheath, was discussed in this paper. The Phoenix sylvestris leaf sheaths were collected from the Phoenix sylvestris tree locations and soaked in water to loosen the fiber. After 3 days of soaking the Phoenix sylvestris leaf sheaths were washed in running water to segregate the PSLSFs. The comprehensive analysis yielded quantitative information on PSLSF, including its tensile strength (192-239 MPa), Young's modulus (1.6-4.3 GPa), improved crystallinity index (53.6%), and cellulose proportion (64.43 wt%). Differential scanning calorimetry (DSC) and thermogravimetric (TGA/DTG) investigations shed light on the thermal stability of PSLSF and showed it durability up to 242 degrees C. Fourier transform infrared spectroscopy (FTIR) evaluation is used to verify the results of chemical assessment. An examination on the exterior texture of PSLSF employing scanning electron microscope (SEM) provided evidence to support the concept of utilizing it as a reinforcing component in composite with substrate as polymers. Research findings indicate that structural applications can benefit from the usage of PSLSF augmented polymeric composite.
