Topic description

Radical photopolymerization processes are widespread in industry (for coatings, paints, inks, varnishes, etc). In addition, zeolites, as microporous aluminosilicates, are widely used in industrial applications such as pollution control, air and water treatment, catalysis, energy transition, molecular separation, and more. As they are obtained in powder form after synthesis, they must be shaped before use on an industrial scale. 3D printing appears to be a very interesting technique for preparing objects with unconventional shape and size to develop new applications and/or increase performance of zeolite.

During this study, the student will have to develop formulations that allow for 3D printing of zeolitic objects. For this, solid photoinitiators such as oxide nanoparticles will be preferred as well as acrylic resin.  The incorporation of ZnO nanoparticles in a resin composed of acrylate monomers and zeolite as fillers could favor indeed a bulk photopolymerization without organic initiator. The large variability of the zeolite material allows different approaches that could be beneficial, e.g. the improvement of the storage stability of the ZnO-based system could be achieved by combining ZnO attached to the zeolite surface. Thus, after decomposition of the polymer, the performance of the zeolite/ZnO composite will be evaluated for pollutant sorption and catalytic photodegradation.

This study takes a multidisciplinary approach to existing know-how in research based on zeolite materials, photo curable resins and nanoscaled ZnO particles which exist on the Institut de Science des Matériaux de Mulhouse. During the study, the student will acquire knowledge on how to characterize polymers and crystallized porous solids.

Presentation of host institution and host laboratory

Institut de Science des Matériaux de Mulhouse (IS2M)

The Mulhouse Materials Science Institute (IS2M) is a CNRS-University mixed research unit located in Haute-Alsace (UMR 7361).  Because of its multidisciplinary character, its scientific impact and the way it interacts with other fields, the laboratory represents one of the structuring forces in the field of Materials and their applications in the academic and industrial world, both at regional and national level. The IS2M has been able to define its identity and acquire unquestionable visibility on the highly competitive landscape of international research.

The IS2M owes its reputation to the excellence of its research, the scientific influence of its Researchers and Research Professors and the enormous professionalism of the research support staff. It also owes it to the attractiveness of the courses in which the Research Professors are involved and to the professional success of its PhD students and post-doctoral researchers.

The general objective of the Institute is to advance the knowledge front and transmit expertise in the field of Surfaces and Interfaces, Functionalization and Porous Materials.

In particular, the Institute aims to be a major player in the development of innovative methods and processes of synthesis, formatting, functionalization and bio-functionalization, in the field of development of characterization methods (specific and/or tailor-made), in the study of interaction mechanisms between a surface and its environment and in the study of correlations of properties on different scales.

The IS2M brings together more than 160 people. Working there are 92 permanent employees including 20 CNRS researchers, 44 research professors, 23 CNRS ITA employees, 5 UHA BIATSS employees and ~70 PhD Students & Post-doctoral researchers/year.
