The Dcarbonize consortium is seeking a PhD students (Doctoral Candidate DC) to work in a multidisciplinary & interdisciplinary team formed by 6 academic research groups 5 companies and 1 industry association offering excellent research and training both in R&D and entrepreneurship.
The DC will be hosted by a network of highly renowned European experts and leading companies in CO2 catalysis and polymer development allowing them to perform cuttingedge research in the most innovative environments and with a multidisciplinary spin involving different topics such as homo and heterogeneous catalysis sustainable monomer/macromolecular design polymer chemistry thermoplastics process scalability depolymerization strategies process optimization and highthroughput approaches.
The Doctoral Candidate (DC) will be working in different individually tailored projects designed to accomplish the three main objectives of the project:DC11AIMPLASISCR2ndRoundfinal.pdf (dcarbonizeproject.eu)
The doctoral programs offered within DCarbonize are funded under Horizon Europes Marie SkodowskaCurie Actions (MSCA) programme
Project Title and Description:
Title:
Synthesis of polycarbonates and polyamides using reactive extrusion (REx)
Description:
To demonstrate the feasibility to produce polycarbonates and/or polyamides by using reactive extrusion (REX) which is considered a greener technology being a continuous process which minimizes and even avoids the use of solvents and also reduces reaction times and overall energy consumption. Alternative monomers capable of being produced from CO2 will be considered to produce those polycarbonates and/or polyamides.
REx has significant value as it is a process that can be easily adapted to an industry infrastructure. The design of these synthetic approaches at AIMPLAS will be addressed considering a broad selection of process parameters and conditions such as residence time temperature screw configuration catalyst type (commercial and developed in the project) in different concentrations and relative ratio of the monomers. The polymers developed will be broadly characterized to evaluate macromolecular mechanical thermal and rheological properties thus in particular molar mass intrinsic viscosity and so on will be monitored.
The studies will be started at lab scale in a Haake Minilab Extruder which will be further evaluated at larger scale in a Brabender rheometer. Technical and economic feasibility has been evaluated in order to test higher scale in twinscrew extruders at pilot plants in AIMPLAS. Additionally and along the technical viability evaluation of scalingup process simulations will be considered by using software such as Ludovic and evaluating the screw designs.
Selected process towards polycarbonates and/or polyamides) will be optimized and obtained polymer material(s) will be characterized indepth. Feasibilities studies will be carried out including a stateoftheart survey to identify a range of biopolymers grades that can be obtained by REX and their potential applications as well as potential market sector.
Thus bearing in mind capabilities and AIMPLAS expertise a review of the obtained material(s) possibilities will be considered for extrusion injection process as well as compounding or suitability towards coating preparation. Technical viability of these possibilities will be discussed to identify needs for further developments. At CNRS polymerization studies will focus on the design of novel CO2sourced polycarbonates and/or polyamides through the synthesis by (co)polymerization in solution or in bulk and characterization of the polymers derived from dienyllactone platform molecules.
Secondment: the project involves a threemonths research stay at TOTAL Energies facilities (Belgium) under the supervision of Dr. Martine Slawinski (the synthesized polymers will be tested in thermoplastic applications).
Enrolment in Doctoral degree: DC11 will be enrolled in UPV (University Politcnica of Valncia) and URennes (University of Rennes) obtaining two PhD titles according to a specific agreement between the two universities.
