Structure and diffusion in DDNs at the nano- to micro- scale
Double-dynamic networks (DDNs) are polymer networks that combine two dynamic modes within the same material offering a wide spectrum of different functionalities. DDNs can comprise one covalent and one reversible network, for example, in order to combine the advantages of both high mechanical strength and easy processability, or they can comprise one network with two different dynamic modes.
In the development of a new class of polymer networks, the investigation of the structure plays a key role, because it represents the linking chain between the synthesis and the final properties of the material. Polymer networks can have inhomogeneities at different length scales, therefore the synergy between multiple characterization techniques is necessary. The combination of probe diffusion and light scattering techniques allows to cover the whole range from the nano- to the micro- scale. In particular, the aim of this research project is to investigate the structure and the diffusion of double dynamic networks, aiming to relate the local diffusion and defects to the mechanical properties.
The systems are handled from the synthesis to the characterization and in particular I am involved in the following aspects:
- Synthesis of double-dynamic networks:
Design and synthesis of a novel double-dynamic network with two different dynamic modes: a metal complex dynamic bond and a thermo-responsive polymer.
- Characterization of double-dynamic networks with light scattering
Light scattering is used to determine the homogeneity of the polymer networks. Moreover, it is used to determine characteristic parameters of the polymer and the network such as the network mesh size.
- Investigation of double dynamic-networks with probe diffusion techniques
Probe diffusion techniques include fluorescence correlation spectroscopy, fluorescence recovery after photobleaching, and dynamic light scattering. With a probe, it is possible to investigate the permeability of the polymer network.
