dc.description.abstract | Poly(ethylene brassylate), a novel inexpensive biodegradable polyester, has been
reinforced with cellulose nanocrystals (CNCs) with the aim of improving its thermal
stability and mechanical properties. The composites have been characterized through
calorimetry, tensile tests, thermogravimetry and electron microscopy. The addition of
small amounts of CNCs improves both the stiffness and the ductility of the composites,
suggesting the existence of some compatibilizing effect. Adding large CNC amounts
increases the Young modulus (e.g., 150% for 50 wt% CNCs), but now the material
shows brittle behavior. Degradation of the CNCs starts at lower temperature suggesting
mutual reactivity. The SEM analysis of the composites with ductile behavior reveals the
formation of a percolating network crossing through the interconnected domains that
conform a PEB-rich continuous phase. Processing consisting on reinforcement
dispersion by sonication followed by melt processing results in composites in which the
improvement of mechanical properties does not involve any trade-off. | es_ES |
