Water as a morphological probe to study polymer-filler interfaces: an original application of thermoporosimetry.

This paper is devoted to the characterization of polymer-filler interfaces by thermoporosimetry using water as a probe. Composites of EVA filled with aluminium hydroxide with high filler content for the required fire retardant properties have been studied. After water sorption at 90 °C, the composites have been analyzed by thermoporosimetry using water as a morphological probe.

Photochemical behavior of polylactide/ZnO nanocomposite films.

This study reports the effect of light on PLA/ZnO nanocomposites films produced by melt-extrusion. The attention focused on the discrimination between the photocatalytic degradation of PLA provoked by ZnO and the UV screening effect of the ZnO nanoparticles. The chemical modifications of PLA induced by UV light irradiation were analyzed using infrared spectroscopy and completed through the analysis of the low-molecular-weight photoproducts using IC and SPME and the characterization of chain scissions with SEC.
