Structural characterization of contractile materials based on electrochemically responsive [c2]daisy chain rotaxanes
Switchable functional molecules capable of producing mechanical work constitute an active focus in nanotechnologies as they can be a source of components for molecular-based devices and materials. In particular, the dynamic nature of mechanically interlocked molecules allows their components to undergo relative internal movements which can be exploited in translation and circumrotation. Over the last few years, our group has demonstrated the possible integration of nano-machines resulting in the formation of responsive materials such as polymer chains, gels or films that can behave as artificial muscles. Within the framework of a FET-OPEN H2020 European project, our current research focuses now on the generation of biomimetic artificial muscles based on electrochemically responsive [c2]daisy chain rotxane polymers for soft robotics. In th current proposal, SANS will be used to investigate the structural changes during the extension and contraction events of our supramolecular polymers as a function of external parameters. Correlations are expected between these environmental changes at the molecular level and the resulting macroscopic properties.
