to verify the crystalline nature of the nanocellulose after the reinforcement and to know the dispersion of nanocellulose in NR matrix
(Fig. 7). The diffractograms of unfilled NR and reinforced nanocellulose were added as references. The diffraction pattern recorded
for a film of nanocellulose displays typical peaks of A-type amylose
allomorph of cellulose I crystalline form [33]. It is characterized
by a strong peak at 2 = 17.9◦ and a very strong peak at 25.07◦.
The natural rubber film displays a typical behavior of an amorphous polymer. It is characterized by a broad hump located around
2 = 19◦.
It is in
