PhD student in Materials Science / Chemistry (H/F)

Updated: 3 months ago
Location: Tremblay en France, LE DE FRANCE
Deadline: 22 Jul 2019

The project will take place between the two institutes, mainly at the CTP for the elaboration of materials and their treatment by chromatogeny, and at CERMAV for structural characterization and vapor phase treatments. CERMAV is a CNRS laboratory located on the Grenoble campus dedicated to the study of polymers derived from biomass (cellulose, chitin, starch, etc.). The "Structure and Properties of Glycomaterials" team, within which the project will take place, has internationally recognized skills and numerous industrial collaborations in the fields of chemical modification, characterization and implementation of these polymers. In addition to the most advanced papermaking techniques, the techniques that are the specialty of CTP characterization will be those developed at CERMAV, namely solid state NMR, electron microscopy and X-ray diffraction. The student will benefit from the know-how and formations of the two Institutes

Cellulose hydrophobization techniques have been developed both with CTP and CERMAV based on the reactivity in gas phase of hydrophobic molecules on cellulose. The two Institutes have developed very complementary approaches based on the one hand on the deposition of reagent on flat substrates, called chromatogeny, with low grafting rates but high hydrophobization efficiency, and on the other hand on weak reagent diffusion in high surface area materials. A project supported by the Carnot Polynat allowed to set up the convergence of the analytical methods used to propose innovative solutions. The aim of this thesis is to go further in both the control of processes and the characterization of materials. For this, new methods will be developed, in particular to evaluate grafting depths, and their relation to functional properties such as barrier properties. Although it is not possible to develop it in this announcement, new functional properties that make the material even more attractive will be developed.
The project will take place between the two institutes, mainly at the CTP for the elaboration of materials and their treatment by chromatogeny at the pilot scale, and at CERMAV for structural characterization and vapor phase treatments. CERMAV is a CNRS own laboratory located on the Grenoble campus dedicated to the study of polymers derived from biomass (cellulose, chitin, starch, etc.). The "Structure and Properties of Glycomaterials" team, within which the project will take place, has internationally recognized skills and numerous industrial collaborations in the fields of chemical modification, characterization and implementation of these polymers. In addition to the most advanced papermaking techniques, the techniques that are the specialty of CTP characterization will be those developed at CERMAV, namely solid state NMR, electron microscopy (both TEM and SEM) and X-ray diffraction. The student will benefit from the know-how and formations of the two Institutes skills.
The candidate should have a solid background in physico-chemistry of polymers and colloids, preferably in chemistry and physico-chemistry of polymers and be familiar with conventional experimental methods of characterization. The profile sought is that of an engineer or master in physico-chemistry of materials or soft matter, with a strong scientific curiosity, a pronounced taste for innovation, a certain autonomy and a taste for teamwork. The knowledge of natural polymers is absolutely not a prerequisite to be able to apply
