Abstract:
      Using graphene oxide（GO） and NR latex as the main raw materials，reduced graphene oxide （RGO）/natural rubber（NR） conductive composites with isolation structure were prepared by freeze-drying technology，and its conductivity properties were studied. The results showed that the isolation structure of RGO was constructed in NR matrix by freeze-drying method，and the AC conductivity and dielectric constant of RGO/NR composites increased with the increase of RGO volume fraction. The isolation structure greatly reduced electrical percolation threshold of the composites and endowed the composites with excellent strainsensitive characteristics.
