在复合结构中采用石墨烯纳米片（GNPL）的益处包括机械特性以及多功能特性。了解GNPL增强复合泡沫塑料的阻抗行为可能会为复合泡沫塑料复合材料开辟新的应用。在这项工作中，GNPLs增强复合泡沫塑料制造和测试的DC和AC电性能。制造并测试了含有0、0.1、0.3和0.5体积%GNPL的四组复合泡沫样品。注意到由于GNPL的添加，复合泡沫的导电性显著增加。交流阻抗测试表明，GNPLs复合泡沫塑料成为频率依赖性的GNPLs的体积分数的增加。随着GNPL的加入，复合泡沫的特性也被观察到从主要的电容性行为转变为主要的电阻性行为。
Benefits of employing graphene nanopletlates (GNPLs) in composite structures include mechanical as well as multifunctional properties. Understanding the impedance behavior of GNPLs reinforced syntactic foams may open new applications for syntactic foam composites. In this work, GNPLs reinforced syntactic foams were fabricated and tested for DC and AC electrical properties. Four sets of syntactic foam samples containing 0, 0.1, 0.3, and 0.5 vol% of GNPLs were fabricated and tested. Significant increase in conductivity of syntactic foams due to the addition of GNPLs was noted. AC impedance measurements indicated that the GNPLs syntactic foams become frequency dependent as the volume fraction of GNPLs increases. With addition of GNPLs, the characteristic of the syntactic foams are also observed to transition from dominant capacitive to dominant resistive behavior.
