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 mm 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.
