♛.2D Janus Hybrid Materials of Polymer-Grafted Carbon Nanotube/Graphene Oxide Thin Film as Flexible, Miniature Electric Carpet.

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