Nowadays, solving the problems associated with environmental pollution is\u00a0of\u00a0special interest. Therefore, in this work, the morphology and thermal and mechanical properties\u00a0of\u00a0extruded\u00a0fibers\u00a0based on polylactic acid (PLA) and poly(butylene adipate-co-terephthalate) (PBAT) added to\u00a0prickly\u00a0pear\u00a0flour (PPF)\u00a0under\u00a0composting\u00a0for 3 and 6 months were evaluated. The highest weight loss percentage (92 +\/- 7%) was obtained after 6-month degradation\u00a0of\u00a0the PLA\/PBAT\/PPF\/CO\/AA blend, in which PPF, canola oil (CO), and adipic acid (AA) were added. Optical and scanning electron microscopy (SEM) revealed structural changes in the\u00a0fibers\u00a0as\u00a0composting\u00a0time increased. The main changes in the absorption bands observed by Fourier transform infrared spectroscopy (FTIR) were related to the decrease in -C=O (1740 cm-1) and -C-O (1100 cm-1) groups and at 1269 cm-1, associated with hemicellulose in the blends with PPF. Differential scanning calorimetry (DSC) showed an increase in the cold crystallization and melting point with degradation time, being more evident in the\u00a0fibers\u00a0with PPF, as well as a decrease in the mechanical properties, especially Young’s modulus. The obtained results suggest that PPF residues could promote the\u00a0biodegradability\u00a0of\u00a0PLA\/PBAT-based fiber composites.<\/p>\n","protected":false},"excerpt":{"rendered":"
