Characterization of the structure and dynamics of the hydrophobic domains in InterPolyElectrolyte Complexes
Advances in polymer science allow to create evermore complex self-assembled polymeric structures which can be interesting e.g. in the field of drug delivery. Interpolyelectrolyte complexes (IPECs) are promising systems owing to their possibility to form hydrophobic domains, which allows incorporating hydrophobic molecules that are otherwise not soluble in water. This competition between hydrophobic and hydrophilic domains have been also observed in polyelectrolyte surfactant complexes (PESCs). The proposed experiment aims to compare the structure and dynamics of the hydrophobic domains in PESCs and IPECs. In IPECs, the hydrophobic moieties are attached to a polymer backbone, which acts as a constraint on the space they can explore and it competes with their tendency to aggregate. Such constraint does not appear in PESCs with non HM-PEs, since the polar heads of the surfactants are free. To characterise the structure of the systems we request 5 days of Neutron Spin Echo measurements on IN15 and 1 day of Small Angle Neturon Scattering on either D22 or D33.
