Graphene is an ideal candidate as a component of flexible/wearable electronics due to its two-dimensional nature and low gate bias requirements for high quality devices. However, the proven methods for fabrication of graphene thin film transistors (TFTs) on fixed substrates involve using a sacrificial polymer layer to transfer graphene to a desired surface have led to mixed results for flexible devices. Here, by using the same polymer layer (parylene C) for both graphene transfer and the flexible substrate itself, we produced graphene TFTs on the wafer-scale requiring less than |2 V| gate bias and with high mechanical resilience of 30,000 bending cycles.
