I graduated from the University of Bordeaux (UB1, France) and received B.S. and M.S. degrees in Organic Chemistry, as well as a postgraduate degree in Polymer Chemistry.
I then conducted my doctoral research on the confinement effects into mesoporous silica and carbon nanostructures at the Intense Pulsed Neutron Source of Argonne National Laboratory (University of Chicago, USDOE) between 2003 and 2005 under the supervision of Professor M.L. Saboungi and received my Ph.D. degree in Chemistry (Materials Science) in 2006 from the University of Orleans (France).
In 2007 I joined the group of Professor J.L. Sauvajol at the University of Montpellier (UM2, France) for a postdoctoral position and I worked with Prof. J.L. Bantignies on the structural and physical properties of epoxy/functionalized carbon nanotubes composite materials.
In 2010 I joined the Advanced Technologies Laboratory Barcelona (ATLB) of Henkel AG & Co. at Universitat Autònoma de Barcelona (UAB, Spain) to work on polymer materials for adhesion applications.

While several attempts have been done in order to obtain a satisfying shaping method for PEEK-based composite material, mechanical and electrical tests have been performed on epoxy-based composite material, with different carbon nanotube weight fraction, and using functionalized and non-functionalized CNTs. In particular conductivity measurements have been done showing a spectacular increase in the case of composite made with 0.50 % in weight of functionalized nanotubes in epoxy.
In our work we used functionalization not only to modify solubility of nanotubes, but also to make covalent links between nanotubes surface and polymer by chemical reaction. Two kind of polymers have been used – thermoset (epoxy) and thermoplastic (PEEK) – and functionalization has been followed using different characterization techniques such as XRD, FT Raman, TEM, XPS and NEXAFS. Then mechanical and electrical tests have been performed.
