Modeling microgels: from microscopic design to macroscopic description

Objective

Soft matter provides the ideal playground for exploring physical phenomena that have no counterpart in atomic and molecular systems. A continuous progress in particle synthesis has provided a rich variety of soft, polymeric colloids, which are highly interpenetrable and can reach ultra-dense, jammed states. Such colloids offer exquisite control of material properties through a change in their internal architecture. Among this new generation of soft particles, microgels – colloidal-scale particles individually made by crosslinked polymer networks – have become a favourite model system for their responsive swelling properties and their multitude of applications. Notwithstanding their potentialities, knowledge of their behaviour from a fundamental point of view is still very limited. The present theoretical description is mostly based on simple models, which do not account for the internal, polymeric nature of the particles. Using state-of-the-art computational techniques across all scales (from atomistic to multi-blob coarse-graining), this 5-years work-program will provide an accurate model of both the microgels and of the effective interactions among them. The model will account for
polymer/solvent interactions and for variation of the external control parameters at all densities, up to jamming conditions. In this way, I will develop a unified framework from the design at the molecular level of the individual particle up to the description of the macroscopic properties of the material. At all steps, I will verify my theoretical progress with experimental measurements performed by world-leading collaborators. This proposal will thus bring the current understanding of microgels to a new level: besides rationalizing existing results, it will open the way for new uses and applications of these fascinating systems.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

ERC-COG - Consolidator Grant

Host institution

CONSIGLIO NAZIONALE DELLE RICERCHE
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
