摘　　要：硅橡胶由于其机械能转化效率高、良好的耐候性、良好的剪切稳定性、低毒性、宽使用温域以及对空气湿度不敏感等因素,成为一种很有应用前景的介电弹性体材料。然而,硅橡胶的低介电常数限制了它作为介电弹性体材料的使用。本文从硅橡胶复合材料、聚硅氧烷与其它聚合物共混、化学修饰聚硅氧烷三方面入手,综述了近些年提高硅橡胶介电弹性体介电常数的研究进展。Silicone rubber has become a promising dielectric elastomer material due to its high mechanical energy conversion,good weather resistance,good shear stability,low toxicity,wide operating temperature range and insensitivity to air humidity.However,the low dielectric constant of silicone rubber limits its use as a dielectric elastomer material.Starting from the three aspects of silicone rubber composites,polysiloxane and other polymer blending,and chemically modified polysiloxanes,the research progress improving the dielectric constant of silicone rubber dielectric elastomers in recent years has been introduced.
