中文摘要:
      目的 对近年来使用改性石墨烯改善聚合物基复合材料介电性能的研究进行总结,指出今后的发展方向。方法 总结通过石墨烯改性来改善其在聚合物的分散性和提高聚合物基石墨烯复合材料介电性能的方法;对比石墨烯/聚合物复合材料的复合工艺对其介电常数和介电损耗数值的变化,总结不同的改性方法对复合材料介电性能的影响。结论 石墨烯作为一种性能较优的导电填料对材料介电性能影响巨大,然而,由于其物理分散性不好,极大地阻碍了石墨烯改性聚合物基高介电复合材料的发展。通过对石墨烯进行功能化改性修饰可以有效提高聚合物基复合材料的介电性能,这种材料可作为电活性聚合物,在很多需要高介电常数的电介质材料领域,如超级电容器、感应器、驱动器、智能包装和机器人等方面得到应用。
英文摘要:
      The work aims to summarize the researches on the dielectric properties of the polymer matrix composites improved with the modified graphene in recent years, and to point out the future development direction. The method regarding the modified graphene used to improve its dispersity in the polymer and to enhance the dielectric properties of the polymer-based graphene composites was summarized. By comparing the effects of compound technology of graphene/polymer matrix composites on the change in their dielectric constants and dielectric loss, the influence of different modification methods on the dielectric properties of the composites was summarized. The results show that as the conductive filler with excellent properties, the graphene has huge influences on the dielectric properties of the materials. However, its poor physical dispersity greatly hinders the development of modified graphene/polymer based high dielectric composites. Through functional modification of grapheme, it can effectively improve the dielectric properties of polymer matrix composites. Such material can be used as electroactive polymer and applied in many dielectric fields requiring high dielectric constants, such as supercapacitor, sensor, actuator, smart packaging and robot.
