Abstract
An infrared adaptive transparent camouflage film includes a substrate, a graphene layer, an electrode layer and an ion gel layer. The substrate has dielectric. The graphene layer is disposed on the substrate and stacked in multiple layer. The electrode layer is disposed over the substrate and is spaced apart from the graphene layer. The ion gel layer is disposed over the graphene layer and the electrode layer, or disposed between the graphene layer and the electrode layer, to dope the graphene layer electrically.
