Effect of Nanometer BaTiO3 on the Mechanical Properties of Dielectric Elastomer Material
Dielectric elastomer actuators(DEAs)have been widely used in biological,medical,and detection applications due to their advantages of fast response,high strain,low power consumption(mW level),and light weight.In this paper,barium titanate(BaTiO3),a high dielectric constant material,was used and doped into a dielectric elastomer material,polyurethane acrylate(CN9021NS),in order to improve the dielectric constant of the material,and the effect of different BaTiO3 particle concentrations on the mechanical properties of polyurethane acrylate was investigated by tensile tests.The experimental results found that the Young's modulus of the material showed an increasing trend as the concentration of BaTiO3 particles increased,and when the concentration of BaTiO3 particles increased to a certain range,its Young's modulus showed a decreasing trend,but it was still larger than that of the specimen without BaTiO3 particles added.
