Structural evolution under stretching of Polyacrylamide-based hydrogels cross-linked by liquid crystalline phases stabilized by Laponite
We aim at determining the structure of Polyacrylamide-based hydrogels cross-linked by nodes made of lipid liquid crystalline phases, here a phytantriol cubic phase, stabilized by clay nanoplatelets of laponite. Such systems have great potential for drug delivery-based applications, since an active substance trapped in the LC phase can be released upon the hydrogel stretching. Hydrogels will be studied both at rest and under uniaxial stretching, using a tensile setup allowing their in situ deformation within the neutron beam. Contrast variation will be used to determine respectively the structure of the clay nanoplatelets of laponite and of the phytantriol cubic phase. This project is the core of the PhD program of Cécile Rerzki-Vérité.
