Description du sujet de thèse

Photochemistry allows for great creativity with a wide range of materials. In this project, a photochemical approach combining photopolymerization and photo-induced synthesis of metallic nanoparticles (NPMs) is being considered to obtain functional metal/polymer coatings. Controlling both NPM synthesis and the multi-scale organic-inorganic organization is a key challenge of the project.
Research Program:
- Synthesis and morphological control of metallic nanoparticles
- Formulation and in situ monitoring of NPM and photopolymer synthesis using UV-Visible spectroscopy, FTIR, etc.
- Development of functional and direct coatings for cosmetic packaging
- Characterization and study of properties: physicochemical, optical, electrical, etc.
Several chemical and photonic parameters will be studied to modulate the morphology of NPMs, their assembly, photopolymerization, and thus their properties.
The project is in close collaboration with an industrial partner in the luxury cosmetics sector.
Expected skills:
- Master's degree in the field of polymer chemistry with good knowledge of photochemistry, composites and nanomaterials.
- The candidate must show a strong interest in working in the laboratory as well as with multidisciplinary teams.

Contexte de travail

The CEMHTI - CNRS laboratory (UPR 3079) proposes a thesis subject registered within the framework of the LUMITEX project financed by the national research agency (ANR) in collaboration with an industrial partner.
The thesis will be carried out within the NaFMAT team "Nano and Functional Materials: from synthesis to applications" belonging to the CEMHTI laboratory, a unit of the Institute of Chemistry (INC) of the CNRS, in Orléans (France)
At the CNRS, the CEMHTI is a specific CNRS research unit (UPR 3079) attached to the Institute of Chemistry (INC), spread over two nearby sites (High Temperature and Cyclotron) and bringing together around 110 people.
The CEMHTI develops expertise and original tools on a national and international level to study in situ the physico-chemical properties of materials in extreme conditions.
The doctoral student will be based on the CEMHTI high temperature site.

Contraintes et risques

- The job will require business travel during the three years of the PhD in collaboration with the industrial partner.
- Work on nanomaterials
