Roll-to-roll hot stamping-electrochemical rapid bubble transfer equipment

　　advantage

　　The roll-to-roll hot stamping-electrochemical rapid bubbling transfer method avoids the conventional transfer process of copper foil etching, and realizes the continuous and non-destructive transfer of graphene from the copper foil growth substrate to the industrial PET flexible transparent plastic substrate Thus, high-quality graphene / PET flexible plastic electrodes were prepared.
