Abstract
The project is based on the formation of supramolecular structure in well-defined conditions and combines new structural and physico-chemical concepts in order to design and then to investigate the intelligent properties of polymeric materials. This research area presents a scientific interest - a better understanding of the nonlinear response to external stimuli - as well as a practical interest - elaboration and characterization of new friendly biomaterials and potential development of commercial products. The supramolecular structures will be achieved by different mechanisms, considering the chains dynamics at the macromolecular level and the interactions exhibited in well-established conditions. Mainly, the efforts are focused on the investigation of polymer materials that are able to respond to the action of external stimuli in a predictable manner by modifying the physico-chemical properties, such as viscoelastic or conformational characteristics, hydrophilic-hydrophobic balance, refractive index, permeability, etc.
For example, the evolution of viscoelastic parameters for multicomponent polymer systems as a function of temperature allows the investigation of in-situ thermal gelation. The hydrogels prepared by the members of the research team since 2011 to present show high elasticity, they recover a large amount of deformation as can be seen from creep and recovery curves illustrated here.
