Research fields

Design of new photoinitiating systems as well as photosensitive resins for specific applications.

J.M.Becht, C. Dietlin, B. Graff, J. Lalevée*, F. Morlet-Savary

*Contact : jacques.lalevee@uha.fr

The development of photosensitive resins for radical or cationic polymerizations or of the preparation of interpenetrated polymer networks require high-level, fundamental investigation of both the photoinitiating systems (e.g. under mild conditions of light irradiation) and each component of the photosensitive resin (e.g. new monomers, hybrid polymerization, stabilizers…).

In fact, it is through a complete optimisation of the photosensitive resin (i.e. photoinitiating system with monomers and other additives) that the final properties of the material created through light irradiation are then enhanced for its use in several fields such as dental materials, surgical glues, functional coatings, building and industrial materials.

The most significant point relies upon the fundamental knowledge of the chemical processes governing the reactivity of these photosensitive resins.

Photopolymerization in dispersed systems

A. Chemtob*, J. Lalevée, J. Poly

*Contact : abraham.chemtob@uha.fr

The polymer industry is going through one of the most significant periods of change in its history. Driven by new environmental regulations, the development of eco-efficient processes and zero-VOC products has become an absolute necessity. In this field, 2 technologies stand out : Polymerization in dispersed media and Photopolymerization. By combining these two main processes, we aim to develop a “hybrid” next-generation technology based on thiol-ene photopolymerization in dispersed media. Advanced manufacturing based on photoreactor promises a wave of high sulphur content dispersed products (films, nanoparticles, porous network). Their outstanding properties open the door to applications responding to current industrial needs such as non-leaching materials, O2 barrier and biobased waterborne coatings, biologically-active particles, hybrid nanosensors and monolithic chromatography column.

Photo-induced macromolecular engineering

*Contact : julien.poly@uha.fr

The introduction of external stimuli in synthetic methodologies has become a very active research axis in the field of macromolecular engineering. In this context, we are developing photo-mediated controlled radical polymerization mechanisms using LEDs as light sources emitting in the visible domain. The efficiency of the developed reactions, such as photocatalyzed ATRP or reversible photolysis combined with RAFT, relies on original catalysts and chain transfer agents and implies the detailed understanding of the underlying mechanisms. Most notably, the temporal control of the reaction makes the deactivation and reinitiation perfectly reversible depending on light irradiation.

Plasma-assisted polymerizations

A. Airoudj, F. Bally-Le Gall, P.Kunemann, V. Roucoules*

*Contact : vincent.roucoules@uha.fr

A plasma produces a wide range of species (molecules, atoms, radicals) in many energetic states (ionized, excited, metastable and fundamental states). These precursors can react or self-assemble to form solid polymeric objects with specific properties. Our aim is to understand and control the mechanisms related to the morphogenesis of complex structures induced during plasma polymerization. The challenge comes from the difficulty in identifying the predominant species leading to the formation of organised units and from multi-scale dimensions of these systems for which chemical and physical phenomena can occur at different spatial and temporal scales.

Fabrication of smart interfaces

A. Airoudj, K. Anselme, F. Bally-Le Gall*, T. Petithory, L. Ploux, V. Roucoules

*Contact : florence.bally-le-gall@uha.fr

The fabrication of functional coatings responding to a (thermal or mechanical) stimulus provides smart properties to the surface of the material. Therefore, the interactions of the latter with its environment can be controlled without changing its formulation. The design of such smart interfaces can be assisted by plasma polymerization and post-modification of functional polymer coatings. For instance, the control of interfacial reactivity has enabled the production of reversible covalent adhesion between two substrates. A simple temperature change enables to assemble or disassemble materials via a plasma polymer functionalized with Diels-Alder reactive groups.

Design of antibacterial surfaces

A. Airoudj, L. Balan, P. Kunemann, L. Ploux*, V. Roucoules

*Contact : lydie.ploux@uha.fr

Our research activities for the development of new antibacterial surfaces rely on both preventive and bactericidal approaches. We aim to achieve high performances in terms of durability of the properties (resistance to ageing, long-term delivery of an active substance) and health and environmental risks (control of the nano-objects, of the delivered doses). What makes our materials and coatings unique is that we favour new antibacterial preventive strategies (e.g. specific mechanical properties) and bactericidal, stimuli-responsive strategies to avoid or restrict delivery of antibacterial but toxic molecules to necessary doses. Both approaches can also be coupled for improved antibacterial performances.

Light-assisted synthesis and physical chemistry of nanocomposite systems

L. Balan*, D. Ivanov

*Contact:lavinia.balan@uha.fr

Light and photochemical reactions are used as very powerful and original tools for “cold” synthesis of nanoparticles (metals, QDs, metal oxides) and nanocomposites, with well-defined morphology. This photo-induced approach also allows temporal and spatial control of the processes. Moreover, innovative multifunctional photo(nano)materials can be obtained via 3D photo-assembling of metal nanoparticles in a wide variety of organic and inorganic matrices.

These new nanomaterials respond to very current issues of miniaturization and integration in fields such as catalysis, optics, photonic, CO2 or H2 storage, pollution control, biology….

Concurrently, an experimental platform was developed for the in situ characterization of nano-objects including several physico-chemical techniques such as nanocalorimetry, X-ray scattering and grazing incidence diffraction using nano-beams.

This platform makes it possible to study the processes of structure formation or complex organisation / reorganisation in various systems ranging from semicrystalline polymers to supramolecular assemblies and hybrid materials.
