Abstract:

A method for dry graphene transfer comprising growing graphene on a growth substrate, chemically modifying a transfer substrate to enhance its adhesion to graphene, contacting the graphene on the growth substrate with the transfer substrate and transfer printing; and separating the transfer substrate with attached graphene from the growth substrate. The growth substrate may be copper foil. The transfer substrate may be a polymer, such as polystyrene or polyethylene, or an inorganic substrate. Also disclosed is the related composite material made by this process.

International Classification:

B41J 2/14

Abstract:

An aspect of the present disclosure provides a system for aerosol jet printing an aerosolized particle source configured to selectively provide aerosolized particles, a nozzle configured to deposit aerosolized particles on a substrate, an actuator configured to generate acoustic energy for migrating the particles, and a generator configured to selectively energize the actuator. The nozzle includes a proximal inlet configured for passage of aerosolized particles, a column configured to focus the aerosolized particles when vibrated by an actuator, and a distal opening configured for deposition of the particles on a substrate.
