Cergy Paris Université

The University

CY Cergy Paris Université (CY) is a French university in the area of Paris (France), born from the fusion between the University of Cergy-Pontoise and the École internationale des sciences du traitement de l’information – EISTI. CY is an attractive centre of teaching and research which hosts international students (25 000 students in 2020). With more than 1000 PhD-hold researchers and 550 Phd students working in 24 research centers, CY is among the most active research centers in France with a high international standard.

The Laboratory

Laboratoire de Physicochimie des Polymères et des Interfaces (LPPI) belongs to the chemistry department of CY and gathers 20 researchers and around 20 PhD and postdoc students. The team is the result of collaboration between chemists, electrochemists, physico-chemists of polymers, surfaces and interfaces. One of the most rewarding achievements of LPPI was to bring together the skills of the research team to develop ionically conducting membranes for electroactive polymers and smart materials. More specifically using interpenetrating polymer network (IPN) architectures, robust, stretchable and highly conducting ionogels have been developed and are at the state of the art in the literature. Such materials allowed LPPI developing highly stable conducting IPN actuators. Thanks to these robust ionogels, LPPI have been able to develop in-air microactuators with the highest speed (1kHz) reported to date. Additionally LPPI used IPN architectures to implement shape memory effect into robust ionogels in order to provide combinations as well as interactions of functions for smarter materials. This recognized expertise in stretchable ionic conducting materials with controlled morphology will be involved in WEAFING to develop stretchable and highly conducting ionogels compatible with textile production.

Dr. Cedric Plesse
Associate Professor

| Workpackage Leader:
Ionogels (WP2) |

Cédric Plesse obtained his Ph.D. (2004) in macromolecular chemistry at the University of Cergy-Pontoise. His research consisted of developing conducting semi-interpenetrated polymer networks to produce actuators. He received in 2005 the French Ph.D. Prize by the Groupe Français des Polymères (GFP). He then joined Prof. Mario Leclerc’s laboratory at the University of Laval (Canada) as a postdoctoral researcher (2004-2006) to synthesize conjugated polymers as transducers for DNA biochips. He was then recruited as Associate Professor at the Laboratory of Physicochemistry of Polymers and Interfaces (LPPI) at the University of Cergy-Pontoise in 2006 and obtained his habilitation (HDR) in 2014. His main research theme concern the development of conducting polymer-based electrostimulable materials, from the synthesis of highly conducting ionogels with interpenetrating polymer network architectures to electromechanical characterization of synthesized (macro or micro) actuators. He has published 51 ranks A papers, 25 proceedings and 3 book chapters (ISI h -index: 22). He (co-) supervised 10 Ph.D. students.

She has published 33 rank A papers and 4 proceedings (h-index: 7). She co-supervised 7 PhD students.

Dr. Frédéric Vidal

Frédéric Vidal received his Ph.D. in polymer chemistry from Lyon University in 1995. He then joined Eindhoven Technology University as a postdoctoral fellow in 1995. He moved to University of Cergy-Pontoise (UCP) as an associate professor in 1997. Currently, he is full professor at UCP, a position he has held since 2008. From 2009 to 2018, he was appointed director of the laboratory of Physicochemisty of Polymers and Interfaces. His research includes development of Interpenetrating Polymer Networks (IPNs), conducting polymers and conducting IPNs based electrochemical devices such as electrochromic devices or actuators.

Dr. Cédric Vancaeyzeele
Associate Professor

Cédric Vancaeyzeele obtained his PhD from University of Cergy-Pontoise in 2004. His doctoral thesis founded by BASF at the LPPI focused on polyisobutene-based IPN. After one year as assistant professor he get a postdoc position at U of Toronto in M.A. Winnik group, where he focused on nanoparticles to develop bio labeling kit for fluidigm inc. Since his assignment in LPPI in 2006 as associate professor, he successfully developed his research focused on the development of nanostructured materials with combined properties for specific applications:
-1 – Development of polyisobutene based semi- IPN for sealing with the BASF Germany
-2 – Materials synthesized by emulsion templating (funding R2DS of the “Ile de France region”).
-3 – Development of anion exchange IPN membranes that protect an air electrode in metal-air battery in (LiO2 and AZTEC projects funded by ANR).
-4- Development of biomaterials based on fibrin IPN (DGA 2009-12 and 2012-15 and ANR Tescan 2013).
-5- Syntheses of bio-based thermoset (LIST collaboration).
He co-supervised 8 PhD and he is co-author of 25 papers + 1 book chapter + 6 patents.

Fengdi Li
PhD Student

Fengdi has graduated from Institut National des Sciences Appliquées de Rouen as an engineer specialized in polymer materials in 2018. After finishing her degree, she joined the WEAFING project as a phD student at LPPI (Laboratoire de Physicochimie des Polymères et des Interfaces) laboratory in Université de Cergy Pontoise. The goal of her work is to develop robust and highly conducting ionogel coatings for the electroactive yarns, allowing their air-operation.

PhD Student

Bin obtained his Ph.D. in polymer chemistry from ChimieParistech-Université PSL in October 2020,majored in thermal stimuli-responsive liquid crystal elastomers (LCEs).
