Water Activated Graphene Oxide Transfer Using Wax Printed Membranes for Fast Patterning of a Touch Sensitive Device
We demonstrate a graphene oxide printing
technology using wax printed
membranes for the fast patterning and water activation transfer using
pressure based mechanisms. The wax printed membranes have 50 μm
resolution, longtime stability and infinite shaping capability. The
use of these membranes complemented with the vacuum filtration of
graphene oxide provides the control over the thickness. Our demonstration
provides a solvent free methodology for printing graphene oxide devices
in all shapes and all substrates using the roll-to-roll automatized
mechanism present in the wax printing machine. Graphene oxide was
transferred over a wide variety of substrates as textile or PET in
between others. Finally, we developed a touch switch sensing device
integrated in a LED electronic circuit
