Fig. 5 shows the storage modulus E0 and the loss modulus E00 of
NR and NR/TRGO composites containing 3 phr of TRGO in the temperature
range from 100 to 0 C. The curve of E0 for all samples
exhibits a single falling corresponding to the glass transition temperature
of NR. Incorporating TRGO causes an increase in modulus
value, being slightly higher for TRGO dispersed in Pluronic F 127. In
addition, a shift of the E00 curve towards higher temperatures was observed in both cases
