高分子化学与材料科学方向博士职位 (PRISM项目)

*PRISM programme* The PRISM (PhD Research Programme for International Training in Sustainable Soft Matter) programme has launched its first call for applications, offering up to 14 fully funded PhD fellowships starting from 1 March 2027 at Paris Sciences & Lettres (PSL) University. The programme trains researchers to address ecological transition challenges through sustainable soft matter science, with projects focused on eco-friendly chemical processes, circular economy, renewable energies, and carbon capture, storage, and valorisation. Co-funded by the European Union under Horizon Europe MSCA COFUND (Grant Agreement 101261637) and partner institutions, PRISM provides interdisciplinary, international, and intersectoral training, including mobility opportunities, secondments, and courses in sustainability, innovation, entrepreneurship, career development, and transferable skills. Applications must be submitted via the PRISM website by 31 October 2026 (23:59 Paris time). *The PhD project* CAPTURE: Development of Smart Materials for Reversible Low-Energy C02 Capture CO ₂ capture, whether from industrial sectors or directly from the atmosphere, has gained significant global attention due to the growing climate crisis. For the last decades, the most widely used CO₂ capture systems have been based on amine scrubbing technology. However, CO ₂ release requires high temperatures and substantial energy input, causing significant amine degradation over time. This limits the economic viability of scrubbing low-concentration CO² sources, such as post-combustion gases and atmospheric air.[1] Much recent work has focused on physically and chemically supported amine-based polymers that can be regenerated under mild conditions.[2] Many sorbents display promising CO₂ uptake capacities thanks to their high surface area. However, few studies have reported solid sorbents effective in humid environments, where water vapor competes with CO₂ for adsorption sites or condenses to block the sorbent’s pores. There is thus a need for nonvolatile sorbents that can operate reversibly under wet conditions and be regenerated at relatively low temperatures. A promising approach by Hoshino and co-workers[3] uses hydrogel micro- and nanoparticles that reversibly absorb and release CO ₂ between 30 and 75 °C. These particles are based on cross-linked copolymers of N-isopropylacrylamide (NIPAm) and acrylamides with pendant tertiary amine groups. Above the lower critical solution temperature (LCST) of the poly(NIPAm) domains, the basicity of the tertiary amines is strongly decreased due to the lower dielectric constant in the dehydrated state. This phase change enables reversible CO₂ capture at low temperatures. However, the low concentration of amine groups results in significantly lower absorption capacity per volume compared to conventional amine scrubbing,[3] and the system lacks sufficient reactivity to capture CO₂ directly from the atmosphere.[4] In this PhD project, called CAPTURE, we aim to leverage the C3M laboratory’s expertise in making functional polymeric materials to dramatically enhance the CO ₂ capture capabilities of thermo-responsive gels. We believe that introducing synergistic functional groups is essential to this new approach. This project will strongly benefit from collaboration with TotalEnergies in the frame of the PICTE joint laboratory with the ESPCI Paris - PSL, working on physical chemistry for the energy transition, as well as an international secondment focused on coupled rheological techniques. The project will entail the synthesis of new hydrogel particles via (controlled) radical polymerization, followed by a thorough study of their physicochemical, thermomechanical, rheological, and morphological properties. Assessing the pKa of the pendant functional groups as a function of composition and temperature will be key to rationalizing their behavior. Reversible CO₂ capture and release experiments will benchmark the performance of these new materials. CAPTURE is expected to result in publications in leading scientific journals, oral presentations at national and international conferences, and potentially patent applications. Our collaboration with TotalEnergies will be critical in guiding the potential industrialization of this technology. References: [1] G. T. Rochelle, Science 2009, 325, 1652. [2] S. Singh et al., J.

Our team already collaborates with Dr. Parisi in the frame of an EU doctoral network called ReBond (HORIZON-MSCA-2022-DN-01, REA Grant Agreement No. 101119786; https://www.rebondproject.eu/). Dr. Parisi is a recognized expert in the linear and nonlinear rheology of soft materials, and he has particular expertise in rheo-Raman techniques. These experiments will be ideal for correlating the structure, viscoelasticity, and CO ₂ capture capabilities of the materials developed in the frame of CAPTURE. INTERSECTORAL : CAPTURE will be conducted in collaboration with TotalEnergies represented by Dr. Stéphane Jouenne, CO ₂ Capture Project Coordinator of TotalEnergies (Pau, FR) and Dr. Enric Santanach-Carreras (HDR), researcher at the Pole d’Etudes et Recherche de Lacq (PERL). Furthermore, CAPTURE will be included in the newly-launched joint laboratory called PICTE (PhysIcoChimie pour la Transition Energétique) between TotalEnergies and several laboratories at the ESPCI Paris - PSL, of which the C3M is a founding member. The research proposed in CAPTURE perfectly addresses a key challenge targeted by the PICTE laboratory, which is to study and optimize the shaping of adsorbent materials for CO₂ capture with a focus on direct air capture (DAC) technologies. These connections with TotalEnergies will be invaluable for guiding the research, creating new scientific collaborations, and creating a stimulating environment for PhD training. The PhD candidate will have extended stays in PERL to grasp the industrial aspects of this topic. INTERDISCIPLINARY : The CAPTURE project is inherently interdisciplinary, traversing concepts of chemistry and physics. It entails molecular and macromolecular organic synthesis, advanced characterization techniques (which cover the chemical, physical, and mechanical aspects of the new materials), polymer processing, and engineering of CO ₂ capture systems.
