In the present work, micropores and a low filler content of Ag@SiO₂ nanoparticles (NPs) are synchronously introduced into polydimethylsiloxane (PDMS) film to obtain porous dielectric elastomeric composites. The morphology and dielectric and mechanical properties of the composites are investigated. The resulting composites possess high dielectric permittivity, low dielectric loss and low Young’s modulus, which is beneficial to the requirements of a dielectric elastomer actuator. This study provides an effective method to prepare high-performance PDMS-based dielectric porous dielectric elastomeric composites filled with low filler contents of Ag@SiO₂ NPs.

在本工作中，将Ag @ SiO ₂纳米颗粒（NPs）的微孔和低填料含量同步引入聚二甲基硅氧烷（PDMS）膜中，以获得多孔介电弹性体复合材料。研究了复合材料的形貌，介电和机械性能。所得复合材料具有高介电常数，低介电损耗和低杨氏模量，这有利于介电弹性体致动器的要求。这项研究提供了一种有效的方法来制备填充有低含量的Ag @ SiO ₂ NPs的高性能基于PDMS的介电多孔介电弹性体复合材料。
