Supramolecular fibres are cellulose derivatives, which are sugar-based polymers. They use silica nanoparticles and cucurbituril 8 (a combination of carbon, hydrogen, nitrogen and oxygen) as composites (National Center for Biotechnology. These fibres have similar mechanical properties to silk based on their strength and ductility as well as their high dampening capabilities.
Oren Scherman –the director of the lab for polymer synthesis at University of Cambridge– stated that the fibres’ extremely uniform 6-micron diameter showed a high potential for reproducibility. The material could be woven into larger sheets due to this reproducible potential. The fibres could also be combined with a photo-crosslinking agent that could reduce swelling, and therefore enable it for external applications.
The chemical self-assembly of the supramolecular fibres in a hydrogel reservoir results in a low-energy manufacturing process.
The scientists created and experimented with the material at the Cambridge University bio-engineering lab. The scientists used a machine to mechanically draw the fibre from a hydrogel reservoir with separating plates, the photo below demonstrates the process used:
As a dampening material, it is a good candidate for energy absorption in buildings. It could be used to absorb vibrations from earthquakes as well as noise. These fibres could be adhered to the joints / interfaces of engineered wood for absorption of earthquake vibrations. The material is highly ductile and can therefore conform to a variety of complex geometries.
