Program
Theoretical part (6 CFU)
- Definition of sustainability, sustainable polymers, Main categories of polymers: biobased and synthetic polymers 0.5 CFU
- Plastics durability and degradation: aging mechanisms (thermal degradation, mechanical oxidation, thermal oxidation, photolysis and photo-oxidation) examples of degradation of some relevant plastics. Polymer stabilization. Evaluation of span life (accelerated ageing, oxidation index, evaluation of induction time) 1 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). 1.5 CFU
- 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. 3 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 composites, by dispersion of additives in a polymer matrix
- Determination of the molecular weight of polymers by viscosimetry
