7. Barrier properties

The main interest in nanocellulose has long focused on the mechanical properties of these nanoparticles and the nanocomposites they produce.

However, there is growing interest in the barrier properties of nanocellulose films, or its nanocomposites, due to the tortuosity produced by nanoparticles, as illustrated in figure 11 .

Because of their size, the surface/volume ratio of these nanoparticles is much higher than that of microparticles.

Most of the materials used in food packaging are derived from non-biodegradable...
