Resumen
[ES]La proliferación del plástico y su mal uso se han convertido en un problema ambiental desde finales del siglo XX. Por ese motivo, es necesario aportar soluciones que permitan compaginar la eficiencia de los plásticos con el respeto al medio ambiente. Poco a poco, distintos sectores industriales apuestan por biopolímeros como el ácido poliláctico (PLA), que cumple todos los requisitos medioambientales para su degradación y nos proporciona muchas de las características técnicas de los polímeros convencionales. Estas características técnicas, además, pueden ser mejoradas utilizando minerales de la arcilla (del tipo de la montmorillonita, Mt) como agente de refuerzo en la fabricación de na nocom posites o nanocompuestos. En este trabajo se han fabricado nanocomposites de PLA reforzado con Mt y se ha evaluado la mejora de algunas de sus propiedades (térmicas y mecánicas) utilizando distintas proporciones de arcilla en peso.

In the last years, the industry sector is investing in biopolymers such as polylactic acid (PLA), which meets all the environmental requirements for its degradation and provides many of the technical characteristics of conventional polymers. These technical characteristics, in addition, can be improved using clay minerals (montmorillonite, Mt) as a reinforcing agent in the manufacture of nanocomposites. In this work, nanocomposites of PLA reinforced with Mt (at different clay loading) have been manufactured and the improvement of sorne of its properties (thermal and mechanical) has been evaluated.
