Postée le 01 juin

Lieu : CEMEF and PERSEE: rue Claude Daunesse, CS 10207, 06904 Sophia Antipolis, France · Contrat : CDD · Rémunération : Gross annual salary: about 26k€ €

Société : Mines Paris-PSL CEMEF

CEMEF, which stands for Centre de Mise en Forme des Matériaux, or Centre for Material Forming, is a leading research centre in the field of material forming. It was created in 1974 and is located in the Sophia Antipolis science park, near Nice in the south of France. It is a research laboratory of MINES ParisTech and has been associated with CNRS, the French National Science Foundation since 1979.
CEMEF develops global approaches in material forming (polymers, bio-polymers, elastomers, metals, alloys...), combining physics, physical chemistry, mechanics, thermics, modelling, numerical simulation (finite element methods, meshing, fluid-structure coupling...). The scientific developments are applied to forming processes: injection molding, extrusion, forging, machining, rolling, welding... It has about 160 people, including 70 PhD students.

Around 15 PhD projects, with industrial collaborations, are anticipated for a start in October.

Description du poste

Project description
Buildings use around 40% of the total energy consumption and generate 35% of total greenhouse gases. This is mainly linked to poor thermal insulation. Poor thermal insulation is also a problem for appliances and pipelines. To change this dramatic situation, high performance insulation materials are needed. The best commercial materials, such as mineral wool and expanded polystyrene, have conductivity between 0.030 and 0.035 W/(m.K). Apart from vacuum insulation panels, only aerogels are “intrinsically” thermal super-insulating materials at the atmospheric pressure (i.e. with thermal conductivity significantly below that of air, 0.025 W/(m.K)) due to their mesoporosity (pore size from 2 to 50 nm) and low density.
Low carbon footprint and “user-friendliness” are also very important factors to consider in addition to material performance. The goal of this PhD project is to develop bio-based materials, bio-aerogels, with very low thermal conductivity using a combined approach of formulation (chemical physics of polysaccharides) and experimental and modelling of material thermal properties. The work will be based on a recently discovered in CEMEF bio-based aerogels with very promising thermal properties.
The work is at the frontier of polymer chemical physics, materials’ processing and understanding of thermal conductivity of porous materials. It will involve the use of various approaches and techniques such as formulation, thermal conductivity measurements, rheology, optical and electron microscopies, characterisation of solutions, gels and porous materials. A certain part of work will be devoted to the basic modelling of thermal conductivity properties.
The work will be performed in two neighbouring research centers of Mines Paris: PERSEE and CEMEF. CEMEF is world leader in the development of biomass-based materials, in particular, in bio-aerogels, and PERSEE has in-depth expertise in aerogels for thermal insulation.
