Rubber tree and oil palmare industrial crops cultivated in the same climate and environment. These plants are used to prepare nanocomposites of natural rubber and cellulose from empty fruit bunches, an abundant residue in the palm oil industry. For this study, the cellulose particles were extracted from the bunches and subjected to enzymatic hydrolysis or microfibrillation to produce nanostructured particles. The nanoparticles were blended with natural rubber latex in an aqueous medium, and the mixture was dried. The properties of the nanocomposites were compared to those of pure natural rubber and unprocessed cellulose composites. The mechanical properties of the natural rubber can be modified by the cellulose content and morphology.As a consequence, it is possible to modulate the material properties by changing only the filler morphology. The use of microfibrillated cellulose hadstronger reinforcement effects. The thermal properties of natural rubber werenot affected by the addition of cellulose. |
