FED cathode structure using electrophoretic deposition and method of fabrication

A method of fabricating a field emission device cathode using electrophoretic deposition of carbon nanotubes in which a separate step of depositing a binder material onto a substrate, is performed prior to carbon nanotube particle deposition. First, a binder layer is deposited on a substrate from a solution containing a binder material. The substrate having the binder material deposited thereon is then transferred into a carbon nanotube suspension bath allowing for coating of the carbon nanotube particles onto the substrate. Thermal processing of the coating transforms the binder layer properties which provides for the adhesion of the carbon nanotube particles to the binder material.

Single-layer and multilayer graphene, method of manufacturing the same, object including the same, and electric device including the same

Graphene is formed with a practically uniform thickness on an uneven object. The object is immersed in a graphene oxide solution, and then taken out of the solution and dried; alternatively, the object and an electrode are immersed therein and voltage is applied between the electrode and the object used as an anode. Graphene oxide is negatively charged, and thus is drawn to and deposited on a surface of the object, with a practically uniform thickness. After that, the object is heated in vacuum or a reducing atmosphere, so that the graphene oxide is reduced to be graphene. In this manner, a graphene layer with a practically uniform thickness can be formed even on a surface of the uneven object.

Method for manufacturing graphene-coated object, negative electrode of secondary battery including graphene-coated object, and secondary battery including the negative electrode

To form graphene to a practically even thickness on an object having an uneven surface or a complex surface, in particular, an object having a surface with a three-dimensional structure due to complex unevenness, or an object having a curved surface. The object and an electrode are immersed in a graphene oxide solution, and voltage is applied between the object and the electrode. At this time, the object serves as an anode. Graphene oxide is attracted to the anode because of being negatively charged, and deposited on the surface of the object to have a practically even thickness. A portion where graphene oxide is deposited is unlikely coated with another graphene oxide. Thus, deposited graphene oxide is reduced to graphene, whereby graphene can be formed to have a practically even thickness on an object having surface with complex unevenness.

Method of printing variable information

The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.
