Scientific summary

- During my Ph.D (IBTH UMR-S 926), my research work concerned the synthesis and the physico-chemical and structural characterization of electrodeposited calcium phosphate prosthetic coatings. Electrodeposition is an innovative process to produce thin calcium phosphate coatings on metallic substrates whose geometry can be simple or complex. The original protocol developed leads to the synthesis of prosthetic coatings with a controlled stoichiometry and whose treatment at an appropriate temperature can produce a monophasic hydroxyapatite (HAP) coating or a biphasic coating made of hydroxyapatite and β tricalcium phosphate (β-TCP). These developments have been transposed to the synthesis of functionalized prosthetic coatings by doping them with a divalent cation, the strontium.

The characterization of these coatings was carried out by various techniques: SEM-EDXS, XRD, TEM, STEM, electron diffraction, corrosion behavior (Tafel and EIS), 3D-SEM (roughness), X-ray map.

 

- Thereafter, my research works (LISM EA 4695) have developped the electrodeposition process by adding amino acids in the electrolytic solution, such as aspartic acid and / or glutamic acid, whose action is known to direct the bone ingrowth in vivo. The results showed a decrease of the size of the electrodeposited calcium phosphate crystals, which leads to the improvement of the prosthetic material behavior in physiological medium, especially of its corrosion behavior. Finally the last developments for the electrodeposition process concerned the synthesis of composite coatings made of a calcium phosphate phase and an organic phase such as collagen or a polymer such as chitosan which is a natural polysaccharide. These elements give the prosthetic coating a chemical composition very closed to that of bones and improved its mechanical properties and its bioactivity.

These new coatings were characterized by various techniques: FEG-SEM, XRD, infrared spectroscopy (FTIR) and Raman spectroscopy.

 

- Afterwards, during a first postdoctoral position (ICMMO UMR 8182), my research works focused on the synthesis of hybrid materials thin films deposited on Si substrates. These materials are made of a SnO2 layer synthesized by metalorganic chemical vapour deposition (MOCVD) and an organic layer synthesized by electrochemical grafting from a diazonium salt (LAMBE UMR 8587). The specific surface properties of these hybrid materials are used for thermoelectric applications and for electrochemical applications such as sensors for the quantification of pollutants in aqueous medium.

These hybrid materials thin films were characterized by several techniques : FEG-SEM, Grazing Incidence XRD, FTIR, XPS, SIMS, AFM and Electroanalytical methods.

 

- During a second postdoctoral position (IJL UMR 7198), my research works focused on the synthesis of oxide coatings for the high temperature corrosion protection of nanostructured  skutterudites materials  (as CoSb3) used for thermoelectric applications. Several techniques were studied to coat the thermoelectric substrate: Chemical Vapour Deposition (CVD), electrochemical anodizing and electrophoretic deposition.

The obtained coatings were characterized by FEG-SEM, X-ray maps and XRD.

 

-Currently, during a third postdoctoral position (MISIS), my research work focuses on the corrosion behaviour in physiological solution of FeMn-based shape memory alloys for implantable devices application.


All of these works have resulted in the publication of a patent, several scientific papers in international journals and a book chapter.
