Polymers in MEMS A – Chemistry, synthesis and applications (2 SWS)

Date and location

Winter semesters. Usually: Thursdays 9:45 - 11:15, AOC 201, building 30.45, Campus South, KIT

Aims of the lecture

The aim of the lecture is providing mechanical or chemical engineers, as well as interested students from the life or material sciences the basic knowledge required for understanding what polymers are and how they are made, highlighting their importance for modern MEMS systems with a wide view to applications in everyday life.

Audience

Bachelor (or equivalent level) students with basic knowledge in material science and chemistry. The lecture will cover all the basics required for understanding the organic chemistry so detailed previous knowledge is not required. Basic understanding of MEMS and its technologies is helpful but not mandatory.

Content

We all come in contact with numerous polymeric products in everyday life. From water bottles to packaging to the cover of the iPad, many things are made of polymers. Polymers are also important materials for modern microelectromechanical systems (MEMS) allowing cost effective mass market compatible products, e.g., in the life sciences or diagnostics. But polymers are not just cost-effective replacements for more expensive classical materials in MEMS (such as, e.g., silicon) – some polymers have intrinsic properties that make them ideal materials for sensors, actuators or templates for biology and chemistry in MEMS.

This lecture will introduce the basics of organic chemistry required for understanding what polymers are, how they are manufactured and which mechanisms are responsible for their unique properties. The lecture will highlight (in the context of MEMS but also in a wider scope) where and why polymers are applied with a strong focus on their chemical and physical properties (and on their synthesis).

Some of the topics covered are:

  • What is the basic chemistry of polymers? What are monomers, what are macromolecules and how are they formed?

  • How are polymers produced on industrial scale – but also on the laboratory scale? Numerous examples of how to make (commonly and lesser known) polymers will be discussed including materials such as Plexiglas.

  • Why are polymers so important for biochemistry and tissue engineering?

  • How do photoresists work and why do some polymers contract when exposed to light?

  • What are high-performance polymers and why do they have such a wide application range, e.g., in implants?

  • What polymers fuel the household 3D printing community and what materials do 3D printers such as, e.g., the RepRap work with?

  • How does 3D printing and rapid prototyping work and which polymers can be employed for which techniques?

  • Why does silicone always smell like vinegar and why is this material so important for modern day microfluidics? How do you built fluid-logic devices using silicone?

  • How do shape memory polymers remember their shape?

  • What are polymer foams and why are they not only important for heat insulation but also for organic chemistry?

  • How do glues work? Why are there two-component glues, what is superglue and how can you make glue from potatoes?

Language

The lecture will be given in German language unless non-German speaking students attend. In this case, the lecture will be given in English (with some German translations of technical vocabulary). The lecture slides are in English language and will be handed out for taking notes. Additional literature is not required.

Preregistration

Preregistration is not necessary.

Exam

The examination will be held in oral form at the end of the lecture. The lecture can be chosen as "Nebenfach" or part of a "Hauptfach". The second lecture of the lecture series "Polymers in MEMS B – Physics, manufacturing and applications" (which is also held in winter semester) can be combined with this lecture as part of a "Hauptfach". In summer semester, the third part of the lecture series "Polymers in MEMS C – Biopolymers and Bioplastics" will be given which may be combined with lectures and B to form a complete "Hauptfach".

This lecture will introduce the basics of physics and material science required for the understanding of the mechanical behavior seen from the engineers view. Micro and nanostructuring of polymers allows the fabrication of micro parts fulfilling their tasks in mostly invisible different applications. But also the fabrication of polymer parts with functional surfaces inspired from Bionics will be presented in this lesson. The lesson will give further an overview over the polymer based structuring processes and will underline the importance by a number of applications e.g. photonic structures or Lotus-like structures.

Some of the topics covered are:

  • How can polymers described from the view of engineers?
  • What are the differences between polymers and metals?
  • Rheology of polymer melts – How does polymer melts flow?
  • How can polymers be formed and demolded?
  • Which structuring processes (replication) processes are available?
  • How does stress influence molded parts (e.g. the deformation of a CD in a hot car)
  • Shrinkage of polymers – which precision is achievable
  • Gluing or welding – How can polymers be assembled?
  • Simulation of replication processes
  • Characterization of polymers – which properties can be measured?

Polymers in MEMS C - Biopolymers and Bioplastics (2 SWS)

Date and location

Summer semesters. Usually: Wednesdays 14:00 - 15:30, room 602, building 10.50, Campus South, KIT

Aims of the lecture

The aim of the lecture is providing mechanical or chemical engineers, as well as interested students from the life or material sciences the basic knowledge of biopolymers and bioplastics, highlighting their importance for modern MEMS systems with a wide view to applications in everyday life.

Audience

Bachelor (or equivalent level) students with basic knowledge in material science and chemistry. Basic understanding of MEMS and its technologies is helpful but not mandatory. Students should also have attended either "Polymers in MEMS A" or "Polymers in MEMS B" during winter semester as this lecture will not provide a general introduction in the chemistry of polymers or polymer processing.

Content

Polymers are ubiquitous in everyday life: from packaging materials all the way to specialty products in medicine and medical engineering. Today it is difficult to find a product which does not (at least in parts) consist of polymeric materials. The question of how these materials can be improved with respect to their disposal and consumption of (natural) resources during manufacturing is often raised. Today polymers must be fully recycled in Germany and many other countries due to the fact that they do not (or only very slowly) decompose in nature. Furthermore significant reductions of crude oil consumption during synthesis are of increasing importance in order to improve the sustainability of this class of materials. With respect to disposal polymers which do not have to be disposed by combustion but rather allow natural decomposition (composting) are of increasing interest. Polymers from renewable sources are also of interest for modern microelectromechanical systems (MEMS) especially if the systems designed are intended as single-use products.

This lecture will introduce the most important classes of these so-called biopolymers and bioplastics. It will also discuss and highlight polymers which are created from naturally created analogues (e.g. via fermentation) to petrochemical polymer precursors and describe their technical processing. Numerous examples from MEMS as well as everyday life will be given.

Some of the topics covered are:

  • What are biopolyurethanes and how can you produce them from castor oil?

  • What are "natural glues" and how are they different from chemical glues?

  • How do you make tires from natural rubbers?

  • What are the two most important polymers for life on earth?

  • How can you make polymers from potatoes?

  • Can wood be formed by injection molding?

  • How do you make buttons from milk?

  • Can you play music on biopolymers?

  • Where and how do you use polymers for tissue engineering?

  • How can you built LEGO with DNA?

Language


The lecture will be given in German language unless non-German speaking students attend. In this case, the lecture will be given in English (with some German translations of technical vocabulary). The lecture slides are in English language and will be handed out for taking notes. Additional literature is not required.
