Hydrogels based on triblock co-polymers made by pluronic F127 display interesting properties: biocompatibility, gelation at room temperature for a possible use as embedding matrixes for bio-organisms, and further developments of biosensors. The inclusion of nanosheets, derivatives from the peeling of layered materials can give further properties (birefringence due to the anisotropy of the 2D shape particles, enhancement of the elastic properties) to the hybrid hydrogels. The association of graphene oxides in hydrogel formed with F127 and its impacts on the gelation mechanisms as well as the elastic properties were investigated. The presence of large inorganic particles spreads out the gelation on a large range of temperature, while conferring to the hybrid materials further elastic properties.
