Description du sujet de thèse

For more than ten years, the world has experienced a resurgence in the number of armed conflicts and an increase in terrorist risks. This threat is notably reflected in the use of old and new generation chemical weapons. Among these chemical agents used as weapons of war are nerve agents (Sarin gas), blister agents (Yperite), or suffocants (phosgene). Civilian or military personal protective equipment (PPE) developed until now generally offers passive protection (capture). A transition to active protection (degradation) is exciting, especially if it provides improved protection by degrading toxic agents in contact with the product while maintaining comfort, lightness, washability, mechanical characteristics, IR stealth and fire protection. The thesis aims to find a compromise between efficiency and textile properties by developing a textile functionalized with innovative porous solid nanoparticles capable of capturing and degrading model toxic agents of the NRBC type. The properties of these materials ensure (i) shaping efficiency (deposition on the fibre), (ii) capture and degradation for a wide range of target molecules, (iii) while guaranteeing excellent compatibility with many synthetic or natural textile fibres to maintain their intrinsic properties. The resistance (mechanical and ageing) of the functional textile will be evaluated by ageing studies, to obtain a fibre that maintains its degradation capacities under rigorous conditions (UV, H2O, temperature, abrasion, perspiration, etc.).

Contexte de travail

This thesis, funded as part of an ANR, will be conducted primarily on the Villeneuve d'Ascq site (UCCS) within the MATHYB team under the supervision of Professors Christophe Volkringer and Christine Campagne (GEMTEX, Roubaix). The innovative nature of this project and its originality also come from the combination of a unique and dynamic partnership between a historic site for textile materials research (GEMTEX), pioneering researchers in the field of porous materials and catalysis (UCCS) and molecular adsorption (ICGM), and a manufacturer of personal protective equipment (Paul Boyer Technologies) able to provide its expertise in the field of manufacturing NRBC protective clothing and its ability to build the specifications of functionalized textiles, integrating the constraints of existing military and technical textiles.

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.
