Ultrathin, freestanding polymer hybrid film with macroscopic sizes and molecular thicknesses have received significant interest due to their applications as functional devices, microsensors or nanoactuators. Herein, it is demonstrated that 2D Janus hybrid materials of polymer grafted carbon nanotubes/graphene oxide (CNTs/GO) thin film was fabricated using micro-contact printed CNTs/GO as photo active surface to grow polymer brushes by self-initiated photografting and photopolymerization (SIPGP) selectively from one side of CNTs/GO film. This achieved 2D Janus hybrid materials with grafted polymer layer as insulative carpet and supported CNTs/GO thin film as conductive element have the potential application as flexible and miniature electric carpet for heating micro-/nano devices locally.
