Graphite Oxide/Polystyrene Blends on Nylon Filter Paper

Graphite oxide/polystyrene blends deposited on nylon filter paper can be flashed through a photomask to produce arrays of interdigitated electrodes (IDE). A team of Northwestern University researchers has found a new way of turning graphite oxide--a low-cost insulator made by oxidizing graphite powder--into graphene, a hotly studied material that conducts electricity. Scientists believe graphene could be used to produce low-cost carbon-based transparent and flexible electronics. This research was supported by a grant from the National Science Foundation.
