(01) Fully Funded PhD Position

PhD position summary/title: Design and synthesis of novel (poly)amines derived from fatty acid derivatives and polyols.

Development of renewable (poly)amines as coupling agents towards the NIPU synthetic pathways using efficient and up-scalable processes by (i) converting aliphatic bio-based polyols into (pluri)amines through the nitrile route and (ii) bio-based polyenes into (pluri)amines via Wacker oxidation and subsequent reductive amination. (iii) Investigation of their polymerization behaviour in NIPU synthesis.

(02) Fully Funded PhD Position

PhD position summary/title: Synthesis of activated carbonate monomers.

o design more reactive carbonated monomers for implementation towards sustainable NIPU processes by synthesizing (i) activated bio-based C5 carbonates having electron withdrawing substituents, in which glycerol carbonate and glycerol monoether will be notably used as intermediates, (ii) 6-membered ring (C6) carbonates by reaction of 1,3-diols with CO2 or dimethyl carbonate, in which larger carbonate rings known to be highly reactive towards aminolysis will be prepared, (iii) 5-membered bis-dithiocarbonates.

(03) Fully Funded PhD Position

PhD position summary/title: Design of NIPUs through transfer reactions and complementary reactions.

To synthesize high molecular weight NIPU (i) by trans-urethanisation of a biobased biscarbamate with renewable diols using organocatalysts such as carbenes or superbases; (ii) by one pot process via an in-situ urethanization of bio-based diamines; (iii) catalytic Lossen rearrangements followed by the transurethanization. Both systems will investigate CO2 and ionic liquids as reaction systems. In an alternative way, building NIPU-based materials via compatible coupling reactions (i.e. acyclic diene metathesis polymerization and others) based on monomers with preformed carbamate moieties (derived via Lossen rearrangement) will be investigated. A mechanical and rheological mapping will be carried out.

(04) Fully Funded PhD Position

PhD position summary/title: Synthesis of functional NIPU oligomers and applications for water- or solvent-free based coatings/adhesives.

To synthesize amino- and cyclic carbonate-bearing NIPU oligomers that are able to react and cure at low temperature when mixed. NIPU oligomers will be prepared by polyaddition of various 5-membered CO2-sourced cyclic carbonates and novel bio-sourced diamines, or by transurethanization. These NIPUs will be exploited for preparing adhesives and coatings from solvent-free and water-based formulations. The adhesion performance of the products on various substrates and structure/properties relationships will be established.

(05) Fully Funded PhD Position

PhD position summary/title: New strategy to produce NIPU foams from reactive formulations.

To develop strategies to self-blowing NIPUs by the in-situ generation of CO2 as blowing agent from an organic precursor prepared by fixation of CO2 to suitable compounds. The reaction conditions & the formulations will be optimized to produce low density microcellular foams with ideally closed cell morphology for thermal insulating applications. Self-blowing NIPU foams will be investigated under solvent-free conditions in molds at ULiege. This process will then be adapted at UBx for reactive extrusion. We will then evaluate the mechanical properties of the foams, as well as their thermal insulating performances & their fire resistance and compare the properties of the foams produced by the two different techniques.

PhD position summary/title: NIPUs recycling and upcycling.

To develop innovative routes for recycling the new NIPUs families by depolymerizing them into small building blocks, followed by their transformation into novel functional polymers (what is called “polymer upcycling”) by sustainable processes. The main challenge in this upcycling step is to establish reaction conditions that will be as sustainable as possible, i.e. in the bulk or in sustainable non-toxic solvents under mild operating conditions. We will then study the thermal and mechanical properties of these new polymers.

PhD position summary/title: Synthesis and foaming of novel NIPUs by continuous reactive extrusion.

To exploit the enhanced reactivity of novel cyclic carbonates including (thio)carbonates towards aminolysis to design NIPUs by challenging reactive extrusion. ESR 7 will set up experimental conditions that answer the kinetics and thermal requirements for NIPUs synthesis by REX (appropriate choice of the monomers, fast molar mass building up, etc.). If required, catalysts compatible with the REX constraints will be searched for boosting the polymerization. Continuous foaming process will be then performed via supercritical CO2 methods. Molecular, thermomechanical, insulating assessments will be envisioned.

PhD position summary/title: Development of biocomposites on basis of NIPU.

To prepare novel biocomposites between cellulose (nano)fillers (nanofibers and nanocrystals) and NIPU thanks to their propensity to set up hydrogen bonding and interfacial covalent cross-linking with them. A special emphasis will be made on nanocelluloses of different shape and surface chemistry in order to efficiently incorporate into NIPU derived from poly(hydroxyl-urethane)s. Surface-chemistry using Fisher pathways will be privileged. Melt-compounding processes will be privileged in this work in order to establish morphological/thermomechanical mapping of resulting (bio)composites.

(09) Fully Funded PhD Position

PhD position summary/title: Functionalized nanocellulose for waterborne NIPU.

To design biocomposites from novel waterborne or solvent-free functional NIPU polymers, where interface aspects and dispersion considerations are emphasized in order to achieve desired properties and processing characteristics. A special emphasis will be placed on waterborne formulations that can be aqueous stable and cured at room temperature from novel activated monomer/amine formulations and/or dual cure systems. Pickering emulsion in the presence of cellulose nanocrystals functionalized via grafting methods will be developed at UBx. The modification is to tailor the interface and control nanocellulose dispersion and biocomposites properties. The purpose of the modification is to tailor the interface and control nanocellulose dispersion in waterborne NIPU.
