Polymer and Colloid Science
Echo dynamic light scattering and rheometer
The Polymer & Colloid Science Group activities are directed
towards the fundamental understanding of the structure-properties
relationship in soft matter. This is accomplished through systematic
approaches on carefully selected projects utilizing a range of powerful,
high spatial and time resolution experimental techniques.
We focus our attention towards model polymeric and colloidal systems
with special consideration to dynamical properties.
The main mastered experimental techniques are scattering
(Light, X-ray, Neutrons) and rheology. As we are not manufacturing
our model samples, we rely on close collaboration with a number
of pioneering chemists. Our effort is also directed towards
the development of specific experimental tools like
Evanescent wave scattering and Echo dynamic light scattering.
The main general interest includes:
- Dynamic of soft systems in dense solutions like polymer
(diblock, rodlike, brush) and colloid (soft and hard) systems,
- Rheology of branched polymers,
- Laser writing in polymer solution.
Current research topics:
- Soft colloids: effective interactions, dynamics and rheology
( G. Petekidis, D. Vlassopoulos)
- Dynamics and non linear rheology of colloidal glasses and gels.
(G. Petekidis, D. Vlassopoulos)
- Macromolecular architecture, self assembly and relaxation
in polymeric systems. (D. Vlassopoulos)
