摘　　要：硅橡胶具有模量低、弹性好、响应快,且其模量在较大温度范围内保持恒定的优点,受到了介电弹性体研究者的广泛关注。然而,硅橡胶介电常数低,用于驱动器时驱动电压高、电致应变小,应用范围受到限制。采用高介电常数的无机粒子填充硅橡胶是提高其介电常数的有效手段之一。综述了常用的高介电无机粒子填充硅橡胶基介电弹性体的研究进展、电致应变性能的影响因素,以及复合介电弹性体的模量增大、介电损耗升高问题及其解决办法。Silicone rubbers have been the focus of researchers in dielectric elastomers due to the well-known characteristics like low modulus,good elasticity,fast response and the ability to maintain their modulus under a wide range of temperatures.However,the intrinsic low dielectric constant of silicone rubbers have contributed to their inadequacy in that high actuation voltage is demanded or low actuation strain is produced while used as an actuator.Filling in high dielectric constant inorganic particles is one of the most effective approaches to improve silicone rubbers'dielectric constants.Research developments of normally used inorganic particles filled silicone rubber systems and factors that may influence the composites'actuation performance were reviewed.Problems as well as solutions related with increase of modulus and dielectric loss of the composites were also summarized.
