摘要

The utilization of easily accessible natural materials and agricultural waste as source ingredients has become essential for the sustainability of composite industries. The present study aims to extract and characterize cellulose obtained through bleaching and acid hydrolysis of Pandanus fascicularis Lam (PFL) fiber. The chemical, morphological, and thermal properties of cellulose extracted from bleached Pandanus fascicularis Lam (BPFL) fiber and acid-treated Pandanus fascicularis Lam (APFL) fiber were studied. A cellulose content of 85.42% was quantitatively determined from BPFL, whereas APFL exhibited a slightly higher cellulose content of 87.59%. Fourier transform infrared spectroscopy (FTIR) study of BPFL and APFL confirms the effective removal of non-cellulosic components. X-ray diffraction (XRD) analysis revealed that BPFL exhibited a crystallinity of 74.5%, whereas APFL exhibited a higher crystallinity of 76.4%. The rough surface morphology of BPFL and APFL was analyzed using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Furthermore, thermogravimetric analysis (TGA) confirms the thermal stability of BPFL and APFL up to 285.2 °C and 280 °C. Exothermic and endothermic transitions of BPFL and APFL were studied using differential scanning calorimetry (DSC). The results show that BPFL, with higher cellulose purity and thermal stability, is suitable as reinforcement in polymer-based biocomposites, offering a sustainable alternative to untreated natural fibers and synthetic fillers. Meanwhile, APFL, with greater crystallinity, can be processed to isolate cellulose nanocrystals for eco-friendly bionanocomposites used in biomedical, pharmaceutical, and packaging applications. Therefore, each extraction method offers distinct advantages depending on the intended application.
