摘      要：Graphene exhibits enormous advantages in mid-infrared(MIR)regulation because of the active control,precise regulation,and large modulation *** graphene films are prepared via chemical vapor deposition(CVD)or reduction,which cannot realize large-scale production and limit the *** films with van der Waals(vdW)structure enable excellent mechanical and electrical performance for flexible electrodes and electronics and might be a candidate for MIR ***,current techniques for preparing vdW graphene films require binder or solution assistance,resulting in chemical residues and performance ***,a new strategy for preparing large-area vdW graphene films by simple mechanical adhesion without any additives was *** selecting the carriers and substrates with proper fracture energies,graphene nanosheets can be transferred from one polymer to another with a layer-by-layer *** obtained graphene films possess desired thickness and comparable electrical conductivity(92.8±4.6 ohm sq–1)with those by chemical vapor *** are of high compactness even for ions to intercalate reversibly,which exhibit excellent electrochemical activity and electro-optical regulation capability,effectively suppressing 90%thermal *** strategy can be extended to prepare high-performance vdW graphene films on various polymer substrates and used for sustainable and smart electro-optical applications.
