Keywords: bio-based biopolymers thermal and mechanical characterization nanocomposites composites with vegetal fibers packaging applications coating applications end-of-life of plastics polymers upcycling

- Synthesis and characterization of new polymers, mainly polyesters and polyamides,homopolymers and copolymers: the synthesis is often focused on the exploitation of natural monomers or monomers derived from renewable resources, waste and recycling of other polymers. Moreover, chemical modifications of existing polymeric chains are carried out in order to introduce functionalites for specific applications. Thermal, mechanical, structural and morphological properties are studied. Relationships between chemical structure, composition and stereochemistry and physical-mechanical properties, biodegradability and photo ageing are studied. The new materials have applications in different fields, such as coating, packaging and biomedical.

- Preparation and characterization of polymeric blends, composites and nanocomposites: the materials are prepared by melt mxing, extrusion, compression moulding or polymerization in situ. The reaserch is focused on composites containing vegetable fibers and nanocomposites containing clay. The thermal and mechanical characterization of the new materials enable us to correlate the chemical characteristics of the filler and its dispersion inside the polymeric matrix with the final performances of the material.

Optimizazion of formulations for industrial applications: according to the requests of final performances of a polymeric material, formulations are studied and optimized
