Abstract

A new conductive rubber composite was fabricated by mixing the ruthenium oxide nanoparticles with silicone rubber. The ruthenium oxide nanoparticles were synthesized by oxidation of metallic ruthenium nanoparticles, which were made using a polyol method. The size of the ruthenium oxide can be tuned by changing the annealing duration in inert atmosphere. It was found that the composite filled with ruthenium oxide of the less size presents more stable piezoresistance recurrence. Based on the random resistor network model and transfer matrix approach, a numerical calculation of the tunneling bonds resistor lattice was conducted to simulate the percolation and piezoresistance behavior of the composite. The simulation shows that the particle size and distribution have strong influences on both the percolative conductivity and the piezoresistance sensitivity.
