Abstract:In this paper, graphene/multi-walled carbon nanotubes (GE/MWCNT) with different ratios were added to natural rubber (NR) by solution blending method, and GE/MWCNT/NR composites with resistance-strain response characteristics were prepared. The dispersion of nanocarbon fillers in the NR matrix was characterized by field emission scanning electron microscopy (FE-SEM), the influence of different GE and MWCNT content on the electrodynamic properties of composite was studied, and finally the interaction between the filler and the matrix was investigated by Fourier infrared spectroscopy (FTIR). Experimental results show that the bonding effect between GE, MWCNT and NR improves the dispersion of the filler in the matrix. Based on experimental and theoretical analysis, the sensitivity, stability and monotonous of resistance-strain responce for the composite with GE was enhanced obviously, and the the optimal content ratio for GE and MWCNT was confirmed as 1:1.
