A multi-functional photo-reduced graphene oxide fabric (rGOf) has been successfully created through an accessible laser direct-write technique at the liquid-air interface. Without the need for any substrate, patternable and porous rGOf can be readily created at the liquid surface through the photoreduction of self-assembled surface graphene oxides (GO). Processing parameters, such as the laser power, printing speed, laser focus, and inclusion of post-processing steps, can lead to tailorable rGOf morphologies. rGOf layering can also lead to the creation of 3-dimensional rGO stacking, further enhancing its functional performance. The as-printed rGOf can be transfer-printed onto any desirable substrates and has demonstrated tremendous potential in energy storage, Joule heating, temperature sensing, humidity sensing, tactile sensing, and ammonia sensing applications.
