Biobased Materials Science

Introduction with incentive/context
Biobased materials play a crucial role in the transition towards phasing out fossil resources. These materials can be made from many different sources/feedstock, possess a wide range of functionalities and can be used in many different applications that currently use fossil feedstock. In order to select the best material for a specific application it is crucial that one understands the underlying science, characteristics and properties of biobased materials. This course addresses the different classes of biobased materials and how their structure and functionality is linked to the raw materials they are made of. A deeper understanding of material functionality will be developed by studying the basic concepts that define the mechanical, rheological and thermal properties of a material. These properties will be translated to manufacturing aspects and use of these materials in different types of (consumer) products. Special attention will be given to the different options to introduce biobased materials in packaging, textiles and furniture. Furthermore insights will be given on how these properties impact the end-of-life (recycling and biodegradation) of these products. Aside from lectures, the learning objectives are supported by a case study and experimental demonstration tutorials so that the course learnings can directly be applied into practice.

• Explain which material properties are important in a specific application and how they may relate or contrast

• Express the concepts and properties that underly processing of a material into a product; basic level for natural materials and in more detail for biobased polymers

• Interpret graphs and figures about mechanical properties and prepare a short experimental plan on how to measure and analyse these properties

• Recognize the material choices that have been made; taking into account aspects such as materials’ structure, properties, processing methods and applications

• Recognize the potential of biobased materials in applications and identify products in which biobased materials are already applied.

• Understand how material mechanical and processing properties translate to the functional requirements and appearance of a product

• Written test with open questions (50%)
• Assignment oral presentation (20%) Ideally a group exists of 6 persons working on one overarching theme (design of a room in a tiny house with biobased materials. Materials properties is the focus of course)). This larger group is split up in groups of 2 to work on a specific topic within that room and will write report on that (mentioned separately).
• Assignment report (30%) In groups of two the students will work on a report on the design (from a materials point of view) of a specific item in a room in a tiny house. The group will write a report (about 10 pages) on this. Three groups together will make a final presentation (see oral presentation)
