Thermo-oxidative stabilization of poly(lactic acid) with antioxidant intercalated layered double hydroxides

2016

Two antioxidant modified layered double hydroxides (AO-LDHs) were successfully prepared by the intercalation of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid (IrganoxCOOH) and 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid (Trolox) in the layered structure of LDH. It was found that by anchoring the phenolic moieties to the LDH layers the antioxidant power is retained in the case of Trolox, and even amplified in the case of IrganoxCOOH. A small amount of the two AO-LDHs was incorporated into poly(lactic acid), PLA, by solution mixing and melt extrusion. The thermo-oxidative stability of the composites was compared with that of the neat PLA and PLA containing free AOs. SEC analy…

Magnetic materials based on layered double hydroxides: chemical design, processing and electrochemical applications

2018

Tras el descubrimiento del grafeno en 2004, los materiales bidimensionales han generado un interés creciente por parte de la comunidad científica que se prolonga hasta nuestros días. Junto a este material constituido por delgadas láminas de carbono, también existen materiales bidimensionales de naturaleza inorgánica entre los que predominan aquellos basados en fuerzas de van der Waals. Dicalcogenuros metálicos, fósforo negro o antimoneno son algunos de estos ejemplos. Sin embargo, también existen materiales 2D formados por láminas iónicas, donde son las fuerzas electrostáticas las que ejercen un papel fundamental en cuanto a la organización y estructura de dichos sistemas. Este es el caso d…
