▎ 摘　　要

Graphene possesses unique features that make it attractive for nanotechnology. Functional devices often require combination of several materials with specific functions, and graphene-polymer composites are one of them. Herein, we report on the preparation of PEDOT:Graphene bilayers by in situ polymerization of EDOT on covalently functionalized graphene. The polymerization proceeds exclusively on the grafted graphene, and patterned structures with high spatial resolution down to 3 mu m could have been prepared. The composite exhibits enhanced efficiency of electrochemical doping compared to pristine graphene, asymmetrical transport characteristic with improved hole-transporting properties and efficient electronic communication between the two materials.
