介电弹性体发电机的发电输出取决于弹性体片的相对介电常数。高介电常数填料如TiO 2填料增加弹性体片的介电常数。为了进一步提高TiO 2/硅橡胶复合材料的介电常数，本文研究了外加电场对TiO 2/硅橡胶复合材料中棒状填料的取向作用。外加交流电场使TiO 2/硅橡胶复合材料的介电常数增大，但不改变TiO 2/硅橡胶复合材料的拉伸应力。通过对TiO 2/硅橡胶复合材料的SEM图像分析，研究了棒状填料的取向。讨论了外加电场对TiO 2/硅橡胶复合材料中填料取向的影响。
Power generation output of dielectric elastomer generator depends on the relative permittivity of the elastomer sheet. High permittivity filler such as TiO2 filler increases the permittivity of the elastomer sheet. In this paper, we investigated the rodlike filler orientation of TiO2/silicone elastomer composite by the external electric field for further increasing the permittivity. The permittivity of TiO2/silicone elastomer composite was increased by the external AC electric field, while the tensile stress of TiO2/silicone elastomer composite did not changed by the field. The orientation of rodlike filler was investigated by analyzing SEM images of TiO2/silicone elastomer composite. The effect of the external electric field to the filler orientation of TiO2/silicone elastomer composite was discussed.
