Program
Theoretical part (6 CFU)
- Definition of sustainable polymer, Main categories : natural polymers (proteins, polysaccharides, lipids, polyesters); synthetic biobased polymers (non biodegradable bioplastics such as bio-PE, PA-11, PTT; biodegradable natural plastics such as PLA, PHA, PBS e sStarch blends, fossil-based biodegradable plastics such as PBAT and PCL. Examples of industrial application. 2 CFU
- Plastics durability: aging mechanisms (mechanical oxidation, thermal oxidation, photolysis and photo-oxidation) examples of degradation of some relevant plastics). Evaluation of span life (accelerated ageing, oxidation index, evaluation of induction time) 2 CFU
- The Problem of plastic Pollution: End-of-life management: classification of recycling typology: primary, secondary, tertiary and quaternary recycle, feedstock recycling. Overview of national and over national policies about plastic recycling (recycling of packaging, of waste electrical and electronic equipment (WEEE) of end-of-life cars (ELV). Polymer in the circular economy. Overview of Life cycle analysis. Examples 2 CFU
Lab experiences (2 CFU)
- Synthesis of polymers through different reaction mechanisms with a specific focus on sustainable, eco-friendly polymers (e.g. dextrin-based polymers)
- Preparation of biomembranes for sustainable processes and study of their properties (permeability tests),
- Preparation of biocomposites, by addition of natural fibers to a polymer matrix
- Determination of the molecular weight of polymers by viscosimetry
- Infrared and thermal characterization of polymer materials by means of FTIR, TGA and DSC analyses.
