Synthesis and Dynamics of Double Networks based on Slide Ring Gels
Our research objective is to design new soft functional materials with improved properties based on the central concepts of double dynamics and slide-ring gels. Targeted key features of these new materials are:
- Easy to process and recycle. Permanent bonds will be avoided. The systems will be in the equilibrium state, avoiding pre-stretching of chains and ensuring better fatigue properties.
- Resist flow and creep. This requires the presence of long-lived or quasi-permanent bonding.
- Dissipate energy to resist fracture. This will be achieved through the presence of supramolecular junctions, which can dissociate and re-associate under shear or extension, bringing viscoelasticity to the materials. In order to modulate relaxation and re-organization of the chains forming the network at will, we will vary the molecular structure of the building blocks. This will promote cooperativity of the supramolecular bonds as well as potential chain entanglements.
- Large “equilibrium” modulus. This requires a dense (i.e. large bond concentration) supramolecular network.
- Double network properties in melt and in solution. This will affect the dynamics of the reversible bonds, as well as the ability of chains to create entanglements, while keeping similar relaxation dynamics.
