Abstract: A method of high-throughput printing and selective transfer of graphene onto a substrate includes the steps of: providing a thermal release tape having graphene adhered thereto; placing a substrate onto the graphene; pressing the thermal tape and the graphene against the substrate at a uniformly-distributed pressure; heating localized portions of the thermal tape and graphene using a localized heat source, thereby diminishing the adhesive properties of the thermal release tape in the localized portions and transferring graphene from said localized portions to the substrate; and separating the thermal release tape from the substrate. The method may include the further step of moving the localized heat source to selected positions on the thermal release tape during the heating step, thereby forming a pattern of heated portions. The method may use a laser beam as the localized heat source, movement of the laser beam being performed by a computer-controlled deflectable mirror.

Abstract: Graphene-carbon nanotube multi-stack three-dimensional architectures (graphene-CNT stacks) are formed by a “popcorn-like” growth method, in which carbon nanotubes are grown throughout the architecture in a continuous step. Alternating layers of graphene and a transition metal are grown by a vapor deposition process. The metal is fragmented and etched to form an array of catalytic sites. Carbon nanotubes grow from the catalytic sites in a vapor-solid-liquid process. The graphene-CNT stacks have applications in electrical energy storage devices, such as supercapacitors and batteries. The directly grown carbon nanotube array between graphene layers provides ease of ion diffusion and electron transfer, in addition to being an active material, spacer and electron pathway.
