Abstract

The electrical properties of solution-processed composite thin films consisting of functlonallzed graphene sheets (FGS) as the filler and polystyrene (PS) as the host material are described. We demonstrate that transistors from graphene-based composite thin films exhibit ambipolar field effect characteristics, suggesting transport via percolation among FGS In the Insulating PS matrix. Device characteristics as a function of the FGS size are also reported. The results Indicate that devices fabricated using the largest size FGS yield the highest mobility values. This simple and scaleable fabrication scheme based on a commodity plastic could be useful for low-cost, macro-scale electronics.
