The axis “Polyelectrolytes”
assembles researchers of the
ICS who study polyelectrolytes
(PEs) and multicharged
systems, in solutions or at
interfaces, and use them to
develop distinct applications in
drug delivery, gene therapy,
sensors, photovoltaic devices
and surface coating. It is specifically worldwide
recognized in the development of the dipped and sprayed
layer-by-layer (LbL) assembly methods that gave rise to
novel nanocomposite and smart materials. It is also a
major area of multidisciplinary scientific research at the
ICS, combining various skills in polymer chemistry,
polymer characterization, polymer physics and
macromolecular engineering at interfaces. Due to the
importance of polyelectrolytes in fundamental aspects of
polymer science as well as in materials science, this area
of scientific research should remain active at ICS in the
next years.

organisation

The projects along this research axis are mainly performed at the ICS thanks to a combination of competences in polymer chemistry, polymer characterization, polymer physics and macromolecular engineering at interfaces. These competences are distributed within three research teams (MPE, IMI and PSM), each one being specialized in more specific subjects such as polyelectrolyte solutions, polyelectrolyte multilayers, layer-by-layer self-assembled films, chemomechanotransductive films, capsules and smart textiles . The experimental techniques used by these teams are : NMR, SEC, FFF, capillary electrophoresis, zeta potential analysis, microcalorimetry, ellipsometry, quartz crystal microbalance (QCM), fluorescence spectroscopy, confocal microscopy, electron microscopy, and small angle scattering (light, X-ray and neutron).
