Flexible nanocrystalline cellulose films (NCC) include a polymer while retaining the property of tunable colour. Polymers, for example PVOH and SB-latex, are effective in increasing the flexibility of the NCC films. The NCC film made with PVOH retains the iridescence better than that made with SB-latex; however, the NCC film made with SB-latex has a better tensile strength. in addition, the NCC film made with PVOH was found to disperse easily in water while the NCC film made with SB latex does not disperse in water (it is strongly water resistant). The colour of NCC film made with PVOH and SB-latex can still be tuned with techniques that provide for tuning.
A flexible, iridescent nanocrystalline cellulose film comprising nanocrystalline cellulose particles in an aligned structure, interspaced by a polymer effective to form flexible bridges between particles without disturbing said aligned structure.
A method of making a flexible, iridescent nanocrystalline cellulose film comprising:
