广东石油化工学院开发出一种高介电常数SBS弹性体复合材料及其制备方法。它是以SBS为基体材料,以纳米石墨片为介电增强功能填料,依次经溶液共混、流延成膜、叠层热压成型后制备获得,其中纳米石墨片占复合材料总体积的0.42%~1.52%。该制备工艺简单且成型方便,所制备的柔性高介电常数弹性体复合材料具有较高的介电常数与较好的柔韧性,适用于制备传感器、触发器、人工肌肉等领域。 Guangdong Institute of Petrochemical Technology developed a high dielectric constant SBS elastomer composite material and its preparation method. It is based on SBS as the matrix material, nano-graphite sheet as a dielectric enhancement filler, followed by solution blending, casting film, laminated hot press molding obtained after preparation, wherein the nano-graphite sheet accounted for 0.42 of the total volume of the composite % ~ 1.52%. The preparation process is simple and the forming is convenient. The prepared flexible high dielectric constant elastomer composite material has high dielectric constant and good flexibility, and is suitable for the fields of preparing sensors, triggers, artificial muscles and the like.
