Confinement and nanostructuration of polymers

-> Version française

Nanostructuration by self-organization of block copolymers

Composed of at least 2 blocks of different chemical nature, block copolymers have the ability to spontaneously form regular morphologies (spheres, cylinders, lamellae) whose typical dimensions typically lay between 5 and 50 nm. We study how this self-organization process is influenced by the confinement in the form of thin films. We develop methods to control morphologies and we implement these patterns through various types of applications.

Nanostructuration by phase separation in blends of homopolymers

The spatial limitation of the phase separation processes favours the formation of nanometric domains. The work focuses on the effects of the process of the films formation and post-processing to control the morphologies obtained. This structuration has been used in particular for deep etching of silicon.

Nanostructuration by deposition of preformed nanoparticles

We study the deposition of preformed nano-objects (spherical nanoparticles, nanorods) on surfaces. We investigate how the deposition mode influences the transfer of nanoparticles to the substrate in order to modify the concentration and the organization of the deposited objects. In this field, our studies focus on the design of nanocomposite films for cosmetic and fuel cell applications and the deposition of Janus nanocylinders forming ordered patterns.

Confinement effect

We carry out fundamental research on the influence of confinement effects on the properties of polymers, such as crystallization behavior, affinity for solvents…
