Transparency has never been integrated into freestanding flexible graphene paper (FF-GP), although FF-GP has been discussed extensively, because a thin transparent graphene sheet will fracture easily when the template or substrate is removed using traditional methods. Here, transparent FF-GP (FFT-GP) was developed using NaCl as the template1. Further, the microstructures of the film were regulated through in-situ reconstruction of the template by plasma2-5. Finally, they were applied in transparent and stretchable supercapacitors, which exhibit enhanced capacitance by nearly 1000-fold compared with that of the laminated or wrinkled chemical vapor deposition graphene-film-based supercapacitors.
