The present embodiment provides an insight on the fabrication and characterization of polymeric dielectric composites for energy storage applications required in mobile electronic devices, stationary power systems, hybrid electric vehicles and pulse power generation. In present study, conducting carbon particles of appropriate dielectric properties have been selectively functionalized with acrylic resin using micro-ballooning method to form core shell conducting particles in order to tailor its conductivity and dielectric properties (dielectric loss in particular). The core shell conducting particles were then mixed with silicone resin in varied proportions (10, 20, 25 and 30 % wt/wt) to form flexible dielectric micro-composites which exemplify concomitant increase in dielectric constant without impairing dielectric loss owing to selective coating of carbon particles via micro-ballooning method. Formulation containing 25wt% core shell conducting particles showed most linear variation in dielectric constant and dielectric loss factor (tan δ) with respect to frequency due to feeble contribution of interfacial polarization.

基于丙烯酸涂层的导电碳颗粒和有机硅弹性体的微复合材料的介电性能

本实施方案提供了对于在移动电子设备,固定电力系统,混合电动车辆和脉冲发电中所需的能量存储应用的聚合物介电复合材料的制造和表征的见解。在本研究中,具有适当介电性能的导电碳颗粒已通过微气球方法用丙烯酸树脂选择性地官能化,以形成核壳导电颗粒,以调整其导电性和介电性能(特别是介电损耗)。然后将核壳导电颗粒与硅树脂以各种比例混合(10、20,25%和30%wt / wt)以形成柔性介电微复合材料,其示例性地伴随着介电常数的增加而不会由于通过微气球方法选择性地涂覆碳颗粒而损害介电损耗。由于界面极化的微弱贡献,包含25wt%核壳导电颗粒的制剂显示出相对于频率的介电常数和介电损耗因子(tanδ)的最大线性变化。
