Effect of the unidirectional drawing on the thermal and mechanical properties of PLA films with different L-isomer content
Velázquez Infante, Julio César; Gamez-Perez, Jose; Franco Urquiza, Edgar A.; Santana Pérez, Orlando Onofre; Carrasco, Félix; Maspoch, Maria Lluïsa Wiley Periodicals, Inc. (2013-02)This work simulates the thermoforming process of two different L-isomer content PLA grades (95.6 and 98%), studying the influence on the induced morphology and the variation in the thermal and tensile properties. The ... -
Fracture behavior of quenched poly(lactic acid)
Gamez-Perez, Jose; Velázquez Infante, Julio César; Franco Urquiza, Edgar A.; Pagès, Pere; Carrasco, Félix; Santana Pérez, Orlando Onofre; Maspoch, Maria Lluïsa BME-PT (2011)The effect of a quenching treatment applied on heated cast sheet extruded films of two poly(lactic acid) (PLA) commercial grades, with different optical purities, was studied. The thermal and mechanical properties of the ... -
Influence of crystallinity on the fracture toughness of poly(lactic acid)/montmorillonite nanocomposites prepared by twin-screw extrusion.
Gamez-Perez, Jose; Nascimento, Lori Miller; Bou, J. J.; Franco Urquiza, Edgar A.; Santana Pérez, Orlando Onofre; Carrasco, Félix; Maspoch, Maria Lluïsa © 2010 Wiley Periodicals (2011-04)The aim of this work was to study the effect of crystallinity degree on the thermal, mechanical, and fracture properties of poly(lactic acid)/organomodified montmorillonite (PLA/OMMT) nanocomposites. Samples with two ... -
