Le jeudi 23 septembre 2021, Maxime BOURGUIGNON présentera l'examen en vue de l’obtention du grade académique de Docteur en Sciences (Collège de doctorat en Chimie) sous la direction de Christophe DETREMBLEUR.

Cette épreuve consistera en la défense publique d’une dissertation intitulée :

« Preparation and characterization of non-isocyanate polyurethane hydrogels and coatings for indoor air decontamination ».

Abstract

This thesis aims to prepare new organic coatings able to reduce formaldehyde by degradation by enzymes under ambient conditions, thus adaptable for indoor life space implementation, using a chemistry that is as green as possible. As enzymes are often inactivated when used out of their natural environment, this work is mainly focused on developing new routes for producing poly(hydroxyurethane)s adaptable for enzyme entrapment by the polyaddition of poly(cyclic carbonate)s to polyamines with the challenge to produce them in water at room temperature without requiring the use of organic solvents. The influence of the structure of the comonomers and the reaction conditions on the formation of the polymer matrix and the entrapment of the formaldehyde degrading enzyme is explored and largely discussed. The potential of the various products as coatings for formaldehyde abatement are also reported.

Le Jury sera composé de :

M. M. GALLENI (Président), Mme et MM. M. ALEXANDRE (Sappi Netherlands Services), H. CRAMAIL (ENSCBP Bordeaux), C. DETREMBLEUR (Promoteur), C. JEROME (Secrétaire), J.-M. RAQUEZ (UMons).
