Nanocellulose was extracted from dried rubber tree leaves and used to reinforce natural rubber. Acid hydrolysis with sulfuric acid (H2SO4) was performed to extract the nanocellulose. The results were compared against nanocellulose prepared from a commercial cellulose source. The synthesized nanocellulose materials were characterized by the transmission electron microscope (TEM) and X-ray powder diffraction (XRD). The produced nanocellulose exhibited needle-like shaped cellulose nanocrystals (CNCs) and demonstrated up to 30% improvement in tensile strength with only 2 wt% CNC addition, along with an increase in elongation at break of natural rubber. Furthermore, despite minor differences in the length of the CNC and crystallinity index, CNCs prepared from rubber tree leaves and commercial cellulose exhibited similar reinforcing ability, which validates CNC via rubber tree leaves source can be an effective reinforcing agent in natural rubber.
