Abstract
The disclosure is directed at a method and system for three-dimensional (3D) printing of flexible graphene electronic devices and deposition of graphene on non-planar surfaces. By using a printer ink that includes a stabilized graphene powder and a pair of solvents, the printer ink provides for a material that overcomes disadvantages of current systems. In one embodiment, the pair of solvents are cyclohexanone and terpineol. The stabilized graphene powder preferably includes a polymer such as, but not limited to ethyl cellulose.
