摘要：
Flexible nanocrystalline cellulose films (NCC) include a polymer while retaining the property of tunable color. 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 color of NCC film made with PVOH and SB-latex can still be tuned with techniques that provide for tuning.
