Sparse networks

Project summary

Cellulose nanofibers have very responsive behavior to even small stresses, and can be applied as coatings, inhalable sprays, and lubricants. Microrheology measurements indicate they are much more efficient than many commercial systems because so little mass is needed to achieve a measurable effect on rheology.

Project objectives

  • Understanding how sparse networks adapt to stress, and ultimately fail, to better apply these fluids to new products
  • Use enzymatic treatments to degrade sparse networks and measure their lower limits of stability
  • Perform 3D imaging of the structures to design new hybrid biological-synthetic materials
