Abstract :
This research aimed to prepare nanocomposite rubber based on silicon rubber and Barium titanate nanoparticles (BTNPs) at different weight content (10,20 and 30 wt.%). The FTIR results indicated that the BTNPs particles dispersed homogeneously in the polymer matrix, and there is no chemical interaction between BTNPs and silicone rubber. XRD analysis demonstrates that the characteristic peaks of all the ingredients of silicone rubber/BTNPs nanocomposite existed. The structural phase of BTNPs within silicone rubber transited from cubic to tetragonal phase after exposure to the electric field. Finally, the open-circuit voltages (Voc) of nanocomposite rubbers after cyclic mechanical stimulations (vertical impact and bending) revealed that the piezoelectricity of samples is influenced by BTNPs percentage. Also, the peak-to-peak voltage (Vpp) significantly increased in the case of the electrically poled silicone rubber/20 wt.% BTNPs.
