K. Cho and co‐workers develop on page 3213 a water‐free transfer method for placing chemical vapor depositiongrown graphene onto arbitrary substrates. Transferring graphene without water enables water‐sensitive substrates to be used in graphene electronics. Using this method, high‐performance flexible air‐stable graphene transistors are fabricated. A polymeric bilayer (poly(methyl methacrylate)/polybutadiene) is used as supporting layer during the transfer process, which provides not only robust support but also effective passivation that protects graphene from undesirable charged impurities.
