The University of Cergy-Pontoise – UCP – is a French university along with 17 other national universities in the Paris area. The UCP is an attractive centre of teaching and research which hosts international students (18,500 students in 2015 – 2016 at UCP with over 1,800 foreign students). With more than 500 PhD-hold researchers and 430 Phd students working in 22 research centers, two Centers of Excellence (Labex) and 6 open labs, UCP is among the most active research centers in France with a high international standard. UCP is part of the Paris Seine University.
Laboratoire de Physicochimie des Polymères et des Interfaces (LPPI) belongs to the chemistry department of UCP 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 litterature. 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.
