The results show that the

• Young’s modulus of the films (Figure 4A) increases with the clay nanofiller content from 5 GPa for pure chitosan up to 11 GPa for the sample Film-4, which contains 40% of clay components. These findings are in good agreement with the mechanical properties of similar composite materials based on sepiolite
