Résumé

Cinnamic derivatives intercalated into ZnAl layered double hydroxides by coprecipitation are subsequently dispersed into a biodegradable polymer, polybutylene succinate (PBS). The structure and composition of the associated organic-inorganic hybrid assemblies are first characterized by X-ray diffraction (XRD) and UV spectroscopy, and then PBS extruded nanocomposite derivatives are evaluated against UV exposure. Using a combination of the PBS nanocomposite structures and the UV and rheological properties relationship, the effect of radiation time on the macromolecular changes undergone by the polymer chains, i.e. chain scissions and cross-linking, as well as on the UV-barrier evolution, is also scrutinized by means of transmission and emission spectroscopies. The combination of organically modified hydrotalcites with PBS could be used as an innovative route for sustainable development of UV protected materials and reduce the environmental impact of UV absorbing chemicals.
