example 1

[0078] A modified (described below) inkjet printer (obtained under the trade designation "HP DESKJET948C" from Hewlett Packard, Palo Alto, CA) was used to transfer weakly bonded crystalline graphite to the substrate. Inkjet printers use dry ink cartridges (that is, the cartridges do not contain any ink). Weakly bonded crystalline graphite (available from Highly Oriented Pyrolyzate of SPI Supplies, Inc., West Chester, PA) was bonded with a binder (available from 3M Company under the trade designation "SCOTCH-WELD INSTANT ADHESIVE CA100"). A 10 mm x 10 mm x 1 mm sample of graphite crystals) was attached to the print head of the ink cartridge. The substrate was a 0.1 mm thick A4 size transparent film (obtained under the trade designation "PVC7204" from LAV Visual Products, Singapore) which was placed in the paper slot of the printing press. When the substrate is drawn into the printing zone by the rollers, the weakly bonded crystalline graphite and the substrate are drawn agains...

example 2

[0080] Example 2 was carried out in the same manner as Example 1, except that, in addition to the print head equipped with weakly bonded crystalline graphite, a second print head was equipped with a paint brush (available under the trade designation "SHUR-LINE PAINT PAD" from Shur-Line of Huntersville, NC (Shur-Line, Huntersville, NC). A paintbrush was attached to the second print head with an adhesive ("SCOTCH-WELD INSTANT ADHESIVE CA100"). A first print head carrying weakly bonded crystalline graphite transfers a thin layer of graphene while in close proximity to the substrate (ie, touching or lightly touching the substrate). During this process, a second print head carrying a squeegee helps thin the graphite and spread the material over otherwise untransferred areas on the substrate. refer to figure 2 , shows a substrate 21 printed with graphene 22 (white area).

Abstract

Article having a first single, discrete atomic, dry layer of a first weakly bonded crystalline material on at least a surface of a substrate. Embodiments of the articles are useful, for example, in automotive under-the-hood parts exposed to chemicals and extreme temperatures

Description

[0001] Cross references to related patent applications [0002] This patent application claims priority to US Provisional Patent Application No. 61 / 421017, filed December 08, 2010, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Graphene, a single carbon atomic layer, is known in the art. Sometimes even several layers of graphene may be referred to as graphene in the art. Two-dimensional (2D) structured carbon sheets of graphene can be carbon isotropes of graphite (three-dimensional (3D) materials), nanotubes (one-dimensional (1D) materials) and fullerenes (zero-dimensional (0D) materials) Aliens provide the basic building blocks. Graphene is predicted to have superior properties such as large thermal conductivity, excellent mechanical properties, and excellent electron transport properties. While not wanting to be bound by theory, it is believed that electrons in graphene follow a linear dispersion relationship an...
