Characterization of Flexible Graphene Oxide Film Reduced by Pulsed Xenon Flash Printable electronics and sensors

Description

Graphene based nanomaterials have an excellent potential to implement in the electronic devices due to its unique and superior electrical, mechanical, and physical properties. The real challenge of using graphene is related to deposition methods and processes which affect dramatically on the final properties. In this study, we present a water-based graphene ink consisting of graphene oxide and polystyrene dissolved in deionized water. The following ink was inkjet printed on oxygen plasma treated Polyimide substrate (Kapton, TM). The fabricated samples were annealed, and then reduced by pulsed Xenon flash within the microseconds ranges and at room temperature. The advantages of replacing Xenon flash reduction instead of conventional methods such as chemical and thermal reduction, are to save time and energy along with the possibility of using various kinds of substrates. The energy, amplitude and width of each pulse were adjusted to achieve the optimum flash settings for the deposited graphene oxide. The reduced samples were characterized to observe the influence of different processing conditions of the reduced graphene oxide films which have the potential to be used as a sensing part in mechanical, environmental or biological sensors.
