the residual char increased in proportion to its nanocellulose content which has a higher residual char
than the NR. When comparing with the thermal stability of the
nanocellulose and NR matrix, we can conclude that the thermal stability can be improved to some extent at the lower filler percentage.
We have a substantial improvement by incorporating nanocellulose in the natural rubber matrix. Even though the thermal
degradation of cellulose starts at 327 ◦C, its degradation in the composite (when it is reinforced in the NR matrix) will start at ∼360 ◦C.
Thus the use temperature range of nanocellulose can be improved
by reinforcing the nanocellulose in the natural rubber matrix.
