In the flexible electronics fields, mounting low resistance printed line on flexible polymer substrates is one of the most headache, because polymer substrates intolerable for annealing process are limited. Here, owing to overcome this mismatch, we transfer the antenna coil (2.89×10^-5 Ωcm) annealed at 250℃ on the glass substrate to the PLA nanosheet (thickness 182 nm, Tg: 55℃) by making use of exfoliation property of multi-stacked graphene flakes. We also demonstrated to operate blue LED mounted on the flexible nanosheet antenna coil wirelessly, even when the flexible antenna coil was folded, twisted and stored in a capsule.
