LPPI Laboratory

The Laboratory of Physicochemistry  of Polymers and Interfaces (LPPI – EA2528) gather teachers-researchers of various profiles: polymerists, electrochemists, inorganic chemists, surfaces and interfaces physicians

Our main expertise concerns polymers networks (interpenetrated) and pi-conjugated (macro) molecules (or conductive electronic polymers) with the specificity of going from the synthesis and physicochemical characterization of materials to their integration in devices, then studied.

These skills and our multidisciplinarity allow us to offer innovative solutions, even technological breakthroughs, on transversal and unifying issues requiring structural materials, functional or stimulables. Today this approach is mainly applied to energy storage and conversion issues, to ”stimulable” materials as well as, more recently, the preservation and restoration of material heritage.

Consideration of problems related to the presence of interfaces as well as understanding the mechanisms of materials ageing studied in working condition, are transversal aspects to all our activities. In the same way, electrochemical modeling and characterization are quasi-systematically used tools when a pi-conjugated system is present in the material. At the same time, The LPPI is one of the founding members of the federative structure “Institut des matériaux”(I-Mat) with three other university laboratories (ERRMECe - Biologie, L2MGC - Génie Civil et GEC - Géo-science).
