I am an experimental physical chemist working in soft matter and colloid science, focused on foams and emulsions. I entered this field during my Master’s Thesis via the problematic of the stability of these systems (surfactant-stabilised emulsions, Pickering emulsions, antifoams, …). My PhD Thesis allowed me to bridge the fields of soft matter and material science by working on the solidification of initially liquid foams using the so-called foam templating method.

Foam templating consists in generating a liquid foam with a controlled morphology in which the liquid phase is a complex fluid that can be solidified. The structure of the liquid foam template and the solidification route set the structure of the solidified foam. As sketched in Figure 1, my research interests revolve around developing a sound understanding of a wide range of phenomena and processes at play for the obtention the “perfect” solid foam from a complex fluid for a given application (often in the biomedical field). Therefore, I investigate how the chemistry (choice of monomer/polymer, cross-linker,…) and physical chemistry (surfactants, additives,…) of the foaming solution will affect the structure and properties of the final polymer foam. Having collaborated for years with physicists, I also became interested in the physics of foaming, developing or adapting foaming methods for the needs of different projects.

Past research

I developed an expertise in the synthesis of macroporous polymers from liquid templates; from the initial formulation and the foaming process to the development of the optimal solidification route (i.e. characterisation of cross-linking kinetics, initiation procedure). I also developed a growing expertise in the characterisation of the morphological and mechanical properties of the resulting solid material. The challenge in such systems is to adapt the chemistry and physical chemistry for the applications aimed at. For example, my latest work led to a patent on CO2-induced cross-linking, in which we show how the foaming gas can trigger solidification.

Current and future research

Following a first collaboration as a postdoctoral researcher with the company Urgo to design foamed wound dressings, I now co-supervise a PhD student working on this project, still funded by Urgo. This project consists in developing a new foam templating route for a biomedical application, implying new scientific constraints and challenges. I also co-supervise a PhD student working on the formulation of polyurethane foams in partnership with BASF. This project focuses on the physical chemistry of polyol mixtures and their additives, with the aim of understanding how the various additives affect the final pore morphology.

However, my research is not solely funded by industries. I am very attached to fundamental research as well. And a recurring challenge I faced in many years of research on foams is the control over the connectivity of the solid foam, i.e., whether the films between bubbles break during solidification. This question remains entirely open, even though the connectivity of foams is a key parameter in determining many of their physical properties (e.g. their absorption, acoustic properties, mechanical properties). Thus, I recently chose to tackle this issue in my current research, which aims at shedding light on the processes involved in the drainage and rupture of thin films during their solidification. I am thus developing a novel microfluidics-based experiment to study how systems known from foam templating solidify in a confined environment. This approach allows me to bridge the science of foams and of film liquid films in the hope of unravelling the mechanisms behind film drainage and rupture.

My research aims at identifying which properties/parameters of each step, from the formulation to the foaming process, may be used as levers to obtain the “perfect foam” for a given application. The fundamental aspect of this research relies on the understanding of structure/properties relations.
