The course aims to provide students with the main theoretical and practical knowledge on the processing and characterisation techniques of bioplastics, which can be used both in the research field and at industrial level. The course includes lectures and practical laboratory exercises on melt processing of polymeric materials (extrusion, filming, injection moulding, spinning), their characterisation and analysis (DSC, TGA, MFI, IR, UV Vis, mechanical and rheological properties, microscopic analysis, surface wettability, disintegration) |
| Reference texts |
Materials provided by the lecturer |
| Educational objectives |
The course aims to provide both theoretical knowledge and practical skills related to the study of polymeric biomaterials. The main knowledge acquired will be related to melt processing techniques (basic elements of extrusion, injection, spinning, filming and fundamental characteristics of the instruments used) and characterisation techniques (basic elements of thermal analysis using calorimeter and thermogravimetric analyser, spectroscopy using UV analysers and an FTIR, electron microscopy and fundamental characteristics of an SEM, wettability of a surface and evaluation by contact angle, disintegration test in bioplastics compost). |
| Prerequisites |
Basic knowledge of chemistry, physics, mathematics, science and technology of polymeric materials |
| Teaching methods |
The materials laboratory teaching mainly involves the application of two teaching methods: lectures and laboratory lessons. In the lectures, theoretical issues related to properties and instrumentation will be addressed, which will then be implemented in the laboratory observations. |
| Learning verification modality |
Oral exam |

| Contents |
The course aims to provide students with the main notions on the structure, mechanical and physical properties, main applications, processing technologies and biodegradation phenomena of thermoplastic, thermosetting and elastomeric biopolymers. At the end of the course the student will be able to correctly choose the most suitable material for each application he/she will have to face, evaluate the advantages and disadvantages of using new biobased materials, study the possibility of realising components with different materials from those currently used, realising savings in economic and environmental terms. |

| Educational objectives |
The course aims to provide students with knowledge on the synthesis, process technologies, use, characterisation techniques of natural, synthetic and composite biodegradable polymeric materials, to provide students with the necessary knowledge to assess the sustainability of a polymeric material, its application and disposal in the environment. The interactions and impact of the polymer with the environment throughout its life cycle will also be studied, interpreting property-structure correlations and predicting the physical and chemical properties of the polymer based on its molecular structure. |
| Prerequisites |
Basic knowledge of chemistry, physics, mathematics, science and technology of polymeric materials |
