Teaching Methods

This module is structured into 8 topics which will be presented in an interactive way. The contents of the module are complementary to those of the Biopolymers and Synthesis and Characterization modules. Whenever possible, demonstrations and/or visits to the laboratories, as well as the resolution of exercises will be included to illustrate the concepts presented in the lectures. Depending on availability, some lectures may be delivered by invited experts.

Learning Outcomes

At the end of this module, students should be able to:

- Apply the concept of macromolecular engineering using tools such as: selection of the mechanism, polymerization technique and functional groups modification

- Describe the main methodologies for preparing polyols, polyesters and polyurethanes from renewable resources

-Describe the main production methodologies for nanocellulose

-Identify key strategies for the chemical and physical modification of cellulose nanofibers and other nanostructured polymers.

-Describe strategies for preparating interpenetrated networks (IPN)

-Discuss the effect of chain length and density of branching and crosslinking on the properties of polymers and derivatives

- Identify the characterization techniques, in this specific context, and deal with the data collected

- Correlate the composition and structures of novel polymers with their properties and innovative applications.
