Figure 2

Optical images of proof-of-concept silver and graphene patterns printed on surface modified Kapton HN substrates with an ethanol-based silver ink and a cyclohexanone/terpineol-based graphene ink, respectively.

(a) and (b) Low (a) and high (b) magnification optical images of the silver interdigitated electrode patterns fabricated by inkjet printing for 5 passes the ethanol-based silver nanoparticle ink on the surface modified Kapton substrates followed by drying at 120 °C for 3 hours. (c) Optical image of the graphene square patterns fabricated by inkjet printing the cyclohexanone/terpineol-based graphene ink for 5 passes on the surface modified Kapton substrates followed by drying at 100 °C for 1 hour.
