摘要
介电弹性体致动器(DEAs)由于具有响应快、应变大、功耗低(mW级)和重量轻等优点,使其广泛应用于生物、医疗、探测等领域。本文使用了钛酸钡(BaTiO_(3))这一种高介电常数材料,将其掺入介电弹性体材料聚氨酯丙烯酸酯(CN9021NS)中以提高材料的介电常数,通过拉伸试验研究了不同BaTiO_(3)颗粒浓度对聚氨酯丙烯酸酯机械性能的影响。实验结果发现随着BaTiO_(3)颗粒浓度的增大,材料的杨氏模量也随之呈现出增大的趋势,当BaTiO_(3)颗粒浓度增大到一定范围时,其杨氏模量出现减小的趋势,但仍大于未掺加BaTiO_(3)颗粒的试样。
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(BaTiO_(3)),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 BaTiO_(3) 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 BaTiO_(3) particles increased,and when the concentration of BaTiO_(3) 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 BaTiO_(3) particles added.
