Offer Description

Supervisors: Sébastien Livi and Jannick Duchet-Rumeau

Applications are invited for a fully funded Postdoc Researcher in the Polymer Materials Engineering Laboratory (Laboratoire d’Ingénierie des Matériaux Polymères-UMR CNRS 5223). The successful candidate will have the opportunity of working on one of the most exciting new concepts in the coating materials arena: how deliver a single material with both outstanding structural performances but also functions.

Today, advanced polymeric materials are at the forefront of tackling global challenges such as environmental issues while pursuing research into high-performance materials. Thus, the development of new synthetic methods is critical for designing innovative polymer materials and proposing sustainable solutions to meet the requirements of the circular economy, i.e. to be durable, reusable, and recyclable. Scientists must thus propose through a 'Functional materials by design' approach to develop molecular brick platforms allowing the integration at the molecular scale of the required functions in the initial synthesis steps. Simultaneously, scientists must think the End-of-Life of these functional materials by the concept 'design to degrade' or ‘design to recycle’, mainly by chemical recycling (degradation or depolymerization into monomers or oligomers) to be reused in a closed loop supply chain or circularity of materials. Recently, the recycling of industrially produced greenhouse gases, such as CO2 , into high value-added chemicals is one of the most relevant strategies to achieve the objectives of reducing global warming and thus limiting climate change. Moreover, CO2 is an inexpensive, non-toxic, non-flammable, and abundant carbon resource, rendering its use in polymer synthesis economically viable at the industrial scale. For these reasons, academic and industrial research is actively working on the development of new polymer materials with the ability to capture CO2 designing a new generation of new smart and (multi)functional-dedicated polymer materials that meet the requirements of sustainable development and even more so for a circular economy is a real challenge. Thus, the approach involves the combination of new molecular architectures fully based on never described ionic liquid monomers allowing the design of thermoplastics or thermosetting networks. Considering a very different concept which consists to the design of new polyfunctional imidazolium monomers bearing different reactive functions, for example epoxy ones, our laboratory has recently highlighted that a multitude of functionalities can be generated from the design of high performances ionic polymer networks. Very recently, an efficient, versatile, and clean methodology was successfully developed to synthesize new mono-, di-, tri- and tetra-epoxydized IL monomers [1-2]. This new route allows to prepare epoxidized ILs at multi-grams scale (10 g to 500 grams) at room temperature with formation of only acetone as inert and volatile by-product. Moreover, our research group had recently demonstrated that the use of epoxidized ILs associated with amine hardeners led to the formation of ionic polymer networks having a glass transition temperature from 50 to 200 °C combined with a full conversion of epoxide groups [3-4]. The ability of such IL monomers to be used as fast-cure reactive systems depending on the cation/anion combination was also highlighted. In addition, antagonistic properties such as stiffness and fracture toughness, combined with self-healing and shape memory capabilities, have been demonstrated [1]. According to this first proof of concept, the objectives of this research will be to design for the first-time smart durable, reusable, and recyclable polyhydroxyurethanes (PHUs).

Applicants should have a strong background in Chemistry and/or Materials Engineering or related fields. A proven aptitude for - and, ideally, experience in - practical experimental work, strong self-motivations and a passion for research are of paramount importance.

Duration of 12 renewable 6 months and net salary of 2200 euros.
