Damage Mechanisms in high voltage insulating polymer materials
I graduated in 2017 from Grenoble Institute of Technology (Grenoble INP – Phelma, France) in the field of physics, materials sciences and engineering. I completed additionally a Master degree at Technische Universität Darmstadt (TUD – Germany), with major in material chemistry and functional materials.
I am currently pursuing a PhD at LPMA, which I started in October 2017, on the topic of insulating polymer materials for high voltage transportation, under the supervision of Solvay, Nexans and Total. My research aims to study the main degradation mechanisms of dielectrics used as insulation materials for power cables, and to link insulation’s lifetime to its microstructure evolution during aging. The study involves the processing of raw polyethylene films with different formulations and microstructures, which are aged under various thermo-electrical stresses. Time to breakdown measurements, associated to investigation of the dielectric, physical and structural properties at different aging stages will bring a novel understanding of the damaging mechanisms under AC fields.
My research interests in general regroup both polymer materials engineering for advanced applications (energy transportation and harvesting, pressure and light sensing) and physical chemistry of organic/inorganic materials at nano-scale (semi-conducting and plasmonic nanostructures, dielectric nanocomposites).
After my PhD. I will look for new challenges, maybe in a different research field. But I would like to keep my interest for applied research in materials, at the boundary between physics and chemistry.
