Research activities

My scientific interests have been focused on Solid State Chemistry of Fluorinated Materials. In addition to the search of new synthetic routes and outstanding physical properties, the effect of nanostructuration and/or surface treatments on the physical-chemical characteristics of materials have also been investigated.
New series of ferrimagnets and ferromagnets : Most series of the families of ferrimagnetic and ferromagnetic fluorides were synthesized and characterized at Bordeaux. The discovery of these new types of magnetic compounds brought big interest to i)solid state physicists for providing experimental objects allowing them to test theoretical magnetic ordering models, ii)crystallographers and solid state chemists because of original architectures consisting of networks of layers, chains, trimers, tetramers, rings, etc.
High or unusual oxidation states in d-transition elements : Ni3+, Cu3+ in cryolite-type phases, Co4+, Cu4+ in K2PtCl6-type compounds can be quoted as examples. The investigation of mixed-valent palladium in Pd2F6 yielded a unique increase of the electrical conductivity by six powers of ten under 50kbars, the highest jump ever observed in à fluoride.
Investigations on various types of carbon-fluorine systems have allowed to approach the fundamental aspects of intercalation processes in graphite and in carbonaceous materials. Most behaviours could be elucidated in terms of charge transfer, electronic configuration of guest species, dimensionality of the magnetic interactions. The outstanding properties can be illustrated by extremely high conductivity values, i.e. in metal fluoride-GICs or in fluorine-intercalated graphite fibres : σ(C10-14F) = 4 x105 Scm-1, approaching the conductivity of copper. In the domain of energy storage, rf-plasma fluorination of carbon anodes allows increasing the capacity of Li-ion batteries by more than 15 %. In primary Li batteries, the use of fluorinated nano-carbon particles (F-NCP) gives higher OCV and suppress the potential delay generally observed during the first time of the discharge reaction with commercial graphite fluorides (Cooperation H. Groult, PHENIX, Sorbonne University).
Effect of nanostructuration and/or surface treatments on the physical-chemical characteristics of materials (Cooperation A. Demourgues, D. Dambournet, E. Durand, ICMCB) can be illustrated in
– Synthesis of thermally stable Al and Fe oxy(hydroxyl)fluorides as catalysts for the synthesis of CFCs substitutes,
– Determination of the electronic transitions at the origin of absorption in the visible range for rare-earth (oxy-)fluorosulfides, and the use of these materials as red or yellow pigments (Rhone-Poulenc patent, 1993),
– New series of oxyfluorinated UV absorbers for the protection of wood and various materials,
– Chemical storage and secured delivery of fluorine (Comurhex-Areva patent, 2006)
– Improvement of surface properties of polymers treated with F2 or fluoro-gases in rf-plasma conditions.

Many of my investigations have been carried out in the scope of varied international cooperations : USA (N. Bartlett (†) ; J.B. Goodenough), Japan (N. Watanabe(†), T. Nakajima , H.Touhara), Russia (I. Flerov, L. Demyanova), Germany (D. Babel).
Beside the importance of the information obtained in all above fields at the fundamental level, numerous applications have been found in the scope of programs with industry, dealing with : catalysis and fine chemistry / medical techniques and biomaterials / nuclear industry / automotive / wood protection/ microelectronics and optics / energy storage, etc.
