Improved Mechanical and Thermal Properties of Date Palm Microfiber-Reinforced PCL Biocomposites for Rigid Packaging

Molecules, Год журнала: 2025, Номер 30(4), С. 857 - 857

Опубликована: Фев. 13, 2025

To increase the use of agricultural residues, such as date palm fibers, for sustainable reinforcement biocomposites, this study investigated incorporation varying weight percentages microfibers (DPMF) ranging from 0 wt.% to 10 into polycaprolactone (PCL) matrix. Biocomposites were fabricated using a combination compression molding and dry blending techniques with without sodium hydroxide (NaOH) alkali treatment. The surface modification was found roughness removing impurities lignin, hemicellulose, wax, while improving crystallinity, evidenced by FTIR, XRD, TGA, particle size analyses. Among different biocomposites investigated, results 5 DPMF content exhibited highest tensile properties: approximately 20% in strength 164% Young's Modulus comparison neat PCL. crystallinity matrix an increasing trend 39% PCL 43% biocomposites. Furthermore, treated demonstrated higher water-repellency behavior improved thermal properties. Dynamic mechanical analysis (DMA) indicated enhanced storage moduli alkali-treated composites; at 35 °C, modulus showed 22% compared untreated reflecting stiffness thermomechanical performances. This highlights potential efficient, eco-friendly alternative fossil-based conventional biocomposite materials' rigid packaging applications.
