| Abstract: |
| Graphene/natural rubber （NR） nanocomposites and carbon nanotubes （CNTs ）/NR
nanocomposites were prepared by wet mixing technology. The effects of the amount of graphene and CNTs on
the properties of NR nanocomposites were studied. The results showed that，with the increase of the amount
of graphene and CNTs，the thermal conductivity and specific heat capacity of NR nanocomposites increased
first and then decreased，the tensile stress at 300% elongation of graphene/NR nanocomposites decreased
at first and then increased，and the elongation at break of the graphene/NR nanocomposites with 2 phr
graphene was the largest. Meanwhile，the tensile stress at 300% elongation of the CNTs/NR nanocomposites
increased with the increase of the amount of CNTs，and the tear strength of the CNTs/NR nanocomposites
with 3 phr CNTs was the highest. With the increase of the temperature，the relative permittivity of CNTs/NR
nanocomposites increased，while the relative permittivity of graphene/NR nanocomposites first increased and
then decreased，reaching the maximum at 110 ℃. |
