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

Through its research into advanced materials and processes, the “Materials Research and Technology” (MRT) department, with its 200 researchers and engineers, contributes to the emergence of enabling technologies that underpin the innovation processes of local and international industry. MRT’s activities hinge on four thematic pillars: nanomaterials and nanotechnology, scientific instrumentation and process technology, structural composites, and functional polymers.

The department also includes four high-tech platforms, focusing on composites, prototyping, characterization and testing. These platforms serve both LIST research staff, and other stakeholders in Luxembourg.

Responsibilities

What you will be doing

Context :

Polyurethanes (PU) are among the most versatile classes of polymers thanks to their remarkable properties such as good adhesion, flexibility, and durability. Despite these advantages, the use of isocyanates in the manufacturing of conventional PUs is a matter of growing concern because these compounds are harmful to humans and the environment, and people exposed to isocyanates can suffer short and long-term health issues. Among various proposed routes for non-isocyanate polyurethanes (NIPUs), the reaction of cyclic carbonate compounds with amines has recently attracted much attention due to the straightforward mechanism. However, the formation of secondary hydroxyl groups as a result of the ring opening of cyclic carbonate renders these materials highly sensitive to moisture. More work must be done to address such issues to ensure the practical utility of these materials. In this context, the aim of this internship is to synthesize NIPUs from bio-based cyclic carbonates via different synthetic methods and to develop novel methods for their modification.


Mission :

The trainee's work will consist of the following steps:

  • Synthesis of bio-based cyclic carbonates
  • Purification of diamines (distillation, sublimation, crystallization) 
  • Optimization of solution polycondensation reaction for the preparation of NIP Us using various diamines
  • Investigation of reactive extrusion for melt synthesis of NIPUs
