PhD in UPtoPARIS MSCA programme : Formulation of self-healing vitrimer membranes


Lieu de travail :

Paris - Ile-de-France - France

Intitulé du sujet :

Formulation of self-healing vitrimer membranes

Champs scientifiques :

- Chimie


Vitrimers, invented in 2011 by the group of Leibler, are chemically crosslinked networks characterized by the presence of exchangeable links, a feature that allows to change topology while keeping the integrity of the network. Vitrimers show unusual combination of properties : they are both insoluble and processable, and flow in the same way as glass at high temperature. This makes them fundamentally recognized as a third and new class of polymeric materials, alongside thermoplastics and thermosets, and on a practical level as a new means of controlling and resolving problems of (re)processing, chemical strength and thermal resistance of materials and composites.
The goal of this project is to design new vitrimers with adequate functionality to ensure efficient transport properties and self-healing. Such materials are heavily needed to develop clean processes in chemical engineering, energy and food industries. The Ph-D student will develop and study new vitrimer formulation compliant with current membrane processes and provided with extended functionality.

3i aspect of the project

This project addresses several KET issues in the field of materials :
Functionalized vitrimer membranes for ion transport offer self-healing properties. Beyond increased performance and durability, self-healing is also valuable as an aid to the assembly of multilayer devices that are ubiquitous in clean energy production and storage systems.
In this project, a priority will be to devise reliable formulations showing efficient ionic transport, easy implementation in the form of thin films, easy assembling and self healing properties. Such a knowledge constitutes a patentable foreground.
This project is at the interface between soft matter chemistry, physics, modelling, chemical engineering and technology applied to energy management. The Ph-D student will also have to deal with aspects related to the protection of intellectual property.
As a rule, PhD students from our laboratory do one or more short internships in a foreign laboratory or, more often, in French or foreign companies with whom we collaborate. e.g. Michelin (France), Schlumberger (United States) , Sabic (Netherlands), Hitachi (Japan).
