Накратко на български

Колоидните системи, като например капки или полимери, се изследват чрез промяна на формата им и влиянието на външни стимули. Това помага да се разбере как структурата на частиците определя свойствата на материали в медицината, храните и козметиката.

Hybrid Colloidal Systems with Designed Response

Colloids find different applications in almost every part of our lives -- medicine, food, cosmetics -- and so it might seem that these systems are fully understood and “tamed”. In reality, this is far from the case! Both fundamental understanding and a clear application strategy are still needed. Nowadays, soft and anisotropic colloids are in high demand, not only due to their rich phase behaviour, but also due to the possibility to control them with various external drives. The main aim of COLLDENSE was to elucidate the relationship between "shape/internal structure/deformability of a single colloid"-"density of the hybrid colloidal system"-"external drive (shear, field, pH)" and the “macroscopic response/phase behaviour of these systems”. The scientific part of COLLDENSE was divided into three scientific workpackages (WPs), according to the hierarchical complexity of the building blocks. The main objective of the WP1 was to understand the behaviour of soft colloids (star polymers, micelles, droplets) in the equilibrium conditions and under mechanical, electric and rheological drives. WP2 was dedicated to the study of hybrid colloids (telechelic stars, dipolar colloids, functionalized droplets). Finally, in WP3, we studied mixtures of various colloids from WP1 and WP2. This combination allowed us to obtain broad knowledge of mechanical and rheological properties of colloidal systems, while simultaneously being able to trace back the dependence on the complexity of building blocks through comparing results obtained in different WPs.

Цел на проекта

The etymology of the word colloid stems from the Greek word for glue. The systematic study of colloids (as we perceive them nowadays) is considered to have begun in the middle of the 19th century. However, the word colloid itself had been mentioned before in very different senses. The development of the physics and chemistry of colloids really took off in the 20th century. Colloids found different applications in almost every part of our lives, and it might even seem that these systems are fully understood and “tamed”. In reality, this is far from the case! Both fundamental understanding and a clear application strategy are required. This is most evident when it comes to the relationship between the nature and arrangement of the colloidal particles and their macroscopic response to an external field (be that shear, electric, magnetic or gravitational fields). To elucidate this relationship we unite 7 academic and 2 industrial partners and 5 associate partners to train 15 ESRs. We aim to develop the concept of COLLoids with DEsigned respoNSE, leading to our acronym: COLLDENSE. Scientific projects are divided into three main workpackeges according to the complexity of the building blocks: deformable colloids, hybrid colloids and colloidal mixtures. The subjects vary from soft repulsive colloids, magnetic colloids, soft microgel particles, telechelic star polymers to droplets with interfaces stabilised by solid particles and DNA nano-constructs. The detailed analysis of mixtures of these components, as well as of their equilibrium and nonequilibrium thermodynamics and rheology, is the other important facet of the project. In order to obtain a complete understanding of the colloidal behaviour under an external drive we employ the three main tools of the modern natural science: experiment, computer simulations and analytical theory. This complete approach will also yield a broad training experience for the young members of the network.
