    • A composite electroactive material having a plurality of particle cores, each particle core surrounded by a polymer covering having one or more strands of an electroactive polymer. In one embodiment, the particle cores have a relatively small size, e.g., between about 10 and 50 nm, and include a material having a relatively large dielectric constant, e.g., greater than about 30. Each polymer strand includes an electroactive elastomer that is bonded to the surface of the corresponding particle core by a linker. Representative examples of the particle core material, elastomer, and linker are titanium dioxide, polybutadiene, and a phosphonate group, respectively.
    • 一种具有多个颗粒芯的复合电活性材料,每个颗粒芯由被一层或多股电活性聚合物覆盖的聚合物包围。 在一个实施方案中,颗粒芯具有相对较小的尺寸,例如在约10至50nm之间,并且包括具有相对较大的介电常数(例如大于约30)的材料。每个聚合物链包含键合的电活性弹性体 通过接头连接到相应颗粒核心的表面。 颗粒芯材料,弹性体和连接剂的代表性实例分别是二氧化钛,聚丁二烯和膦酸酯基。
