Abstract

The rubber nanocomposites based on NR/CR blends and CNT were prepared by the two methods. By the first method, the surfactant was used for dispersion of CNT in NR latex then NR/CNT mixtures, CR and other fillers were mixed using a mixer. By the second method CNT and the rubber components were separately dispersed in toluene and then mixed together. After that the rubber/CNT mixture and other fillers were further mixed using a mixer. The rubber nanocomposites were vulcanized at 145 oC for 20 min. The results reveal that CNT were well dispersed in rubber blend by FE-SEM images. The optimal CNT content for reinforcement of NR/CR blend was 3 % and the mechanical properties of the NR/CR blend were significantly improved. The tensile strength, the thermal decomposition temperature increased about 50.3 % and 8 oC, respectively. The electrical percolation threshold of the materials was reached at CNT content of 4 % with the electrical conductivity of 10-5 S/cm.
