- wojkiewicz jean-lucJean-Luc Wojkiewicz is HDR in physical sciences (2012) and PhD in material science (1984), he is elected as Professor in September 2013 and gives lectures in general physics at Institut Mines Telecom Lille Douai. He created the conducting polymer laboratory in 1992 and joined the Atmospheric Science and Environment Engineering in « Institut Mines Telecom ». His research interests are focused on the synthesis, electronic, electromagnetic studies of nanostructured conducting polymers. In the frame of international collaborations, new electronic organic gas sensors were optimized to get extremely low detection threshold for atmospheric pollutants detection. Now, he is working on the development of new nanostructured materials based on polyaniline/Graphene nanocomposites to detect Volatile Organic Compounds at extremely low concentration which can be integrated in an e-nose. These material performances are used for medical diagnosis to detect diseases (cancer, renal failure..) by breath analysis. Other applications are also investigated as flexible antennas, electromagnetic shielding or radar absorbing materials.
