Many properties of synthetic and biological materials are governed by interactions and processes over several length- and time-scales. These time-/length-scales need to be recognized in order to understand fundamental physical processes such as wetting, transport of charge in organic materials, and crystallization.
Multiscale approaches therefore naturally encompass and pose new challenges in synthesis, structure formation, characterization, simulation and theory of soft matter.
Multiscaling – i.e. understanding, and ultimately controlling, systems on a wide range of length- and time-scales – is essential for a number of scientific questions that we are currently researching:
- How are heat, matter and charge transported organic semiconductors?
- How can the efficiency and operational lifetimes of blue organic light emitting diodes (OLEDs) be improved?
- What is the mobility of molecules and nanoparticles in porous materials, gels and polymer solutions?
- How can one fabricate robust super liquid repellent surfaces?
- How can one overcome the ultra-large equilibration times to study long chain polymer melts?
- How can we make sure that polymeric nanoparticles penetrate into the tumor?
Questions like these can only be successfully addressed by considering several length and time scales. At our Institute, we are tackling these challenges in a combined experimental and theoretical approach.
