Your work environment

The Luxembourg Institute of Science and Technology (LIST) is a Research and Technology Organization (RTO) active in the fields of materials, environment and IT. By transforming scientific knowledge into technologies, smart data and tools, LIST empowers citizens in their choices, public authorities in their decisions and businesses in their strategies.

You will be part of the LIST Materials Research and Technology department

Through its research into advanced materials and processes, the department, with over 190 researchers and engineers, contributes to the emergence of enabling technologies that underpin the innovation processes of local and international industry. The department’s activities hinge on four thematic pillars supported by dedicated platform specialists as below:

  • nanomaterials and nanotechnology,
  • scientific instrumentation and process technology
  • structural composite materials and manufacturing
  • and functional polymer unit





The 18 months post-doctoral project will focus on the processing of elastomer/thermoplastic blends having high differences in viscosity through innovative extrusion process. A special focus will be put on interfacial compatibility and structure-property in-depth characterization.


The multi-disciplinary project will aim at improving thermoplastic-elastomer blends by adapting process conditions and formulations. With this view, a good knowledge of industrially available thermoplastic properties would be appreciated. Improvement of elastomer / thermoplastic compatibility will also be studied by reactive melt-processing. The obtained blend will then be compounded with fillers and vulcanization additives in order to evaluate final properties.

Characterization will include thermo-mechanical properties: heat deflection temperature, stiffness, ductility, fatigue resistance, glass transition, crystallinity and also adhesion, morphology, rheology and ageing.
