以十八胺功能化石墨烯(GE-ODA)为填料，制备了PS和PMMA的不相容共混物导电复合材料。结果表明，当PS和PMMA相形成共连续结构且GE-ODA纳米片选择性定位并在PS相中形成逾渗网络时，复合材料的电导率可以达到最优。对于PS/PMMA(50w/50w)共混物，表现出极低的电逾渗阈值(0.5 wt%)。

PS and PMMA blends filled with GE-ODA have been fabricated to obtain conductive composites. The electrical conductivity can be optimal when PS and PMMA phases form a cocontinuous structure and GE-ODA nanosheets are selectively located and percolated in the PS phase.
