PhD tittle : Conception of polymers actuator to elaborate reconfigurable membranes in situ.
Summary of research project :
The objective is to prepare membranes able to adapt their intrinsic characteristics in operando
thanks to the integration of polymeric actuators. Polymeric actuators are materials that change, in a
reversible way, their shape and volume in response to an environmental modification [1-3]. The
external stimuli of theses responsive polymers materials may be the temperature, mechanical or
electrical stress, magnetic field, light (UV) and chemical exposure [2,3] (pH, solvent, moisture). The
change in volume and/or in shape can be observed at nanometric scale as well as macroscopic level.
The purpose of this PhD is thus to integrate polymeric actuators to the structure of a filtration
membrane allowing its partial or total reconfiguration on request. As an example, a polymer actuator
will be localise inside the membrane pores to control their number, size and shape (see figure). It will
be also possible to localize actuators at the membrane surface to modify its roughness and thus
enable changes in permeability (surface chemistry, contact chemistry) but also to facilitate
unclogging operations. Finally, actuators will be integrated in the bulk membrane to study more
significant structural configurations with the aim to elaborate stimulables nanomembranes.
