我们报道了在非导电二氧化硅纳米颗粒的加入后，多层石墨烯(MLG)/聚苯乙烯复合材料的电导率大幅增加。非导电填料起到了高效分散助剂的作用，防止片状MLG在用于制备复合材料的溶剂浇注过程中重新堆积或结块。与没有这种填料的样品相比，MLG的增强分散性导致电导率提高了几个数量级。
We report a massive increase in the electrical conductivity of a multilayer graphene (MLG)/polystyrene composite following the addition of nonconducting silica nanoparticles. The nonconducting filler acts as a highly effective dispersion aid, preventing the sheetlike MLG from restacking or agglomerating during the solvent casting process used to fabricate the composite. The enhanced dispersion of the MLG leads to orders of magnitude enhancement in electrical conductivity compared to samples without this filler.
