摘要： A rolling contact layer-by-layer assembly device comprises at least one roller, a cylinder substrate and a motor to rotate the cylinder substrate. The assembly device optionally includes at least one rinsing nozzle and air applicator. The rollers each provide a polyelectrolyte solution to the surface of the cylinder substrate, the polyelectrolyte solutions having an affinity for each other. Excess polyelectrolyte solution can be washed using the rinsing nozzle followed by a drying step prior to the application of the second polyelectrolyte solution. A plurality of bilayers is produced by the continuous application of polyelectrolyte solutions to form an LBL article such as a nano-composite article or film. The film is then removed from the surface of the cylinder substrate.

摘要： A method and system for aligning nanotubes within an extensible structure such as a yarn or non-woven sheet. The method includes providing an extensible structure having non-aligned nanotubes, adding a chemical mixture to the extensible structure so as to wet the extensible structure, and stretching the extensible structure so as to substantially align the nanotubes within the extensible structure. The system can include opposing rollers around which an extensible structure may be wrapped, mechanisms to rotate the rollers independently or away from one another as they rotate to stretch the extensible structure, and a reservoir from which a chemical mixture may be dispensed to wet the extensible structure to help in the stretching process.

摘要： Certain example embodiments of this invention relate to methods for large area graphene precipitation onto glass, and associated articles/devices. For example, a coated article including a graphene-inclusive film on a substrate, and/or a method of making the same, is provided. A metal-inclusive catalyst layer (e.g., of or including Ni and/or the like) is disposed on the substrate. The substrate with the catalyst layer thereon is exposed to a precursor gas and a strain-inducing gas at a temperature of no more than 900 degrees C. Graphene is formed and/or allowed to form both over and contacting the catalyst layer, and between the substrate and the catalyst layer, in making the coated article. The catalyst layer, together with graphene formed thereon, is removed, e.g., through excessive strain introduced into the catalyst layer as associated with the graphene formation. Products including such articles, and/or methods of making the same, also are contemplated herein.

摘要： Nanostructured assemblies are manufactured by condensing an evaporated wetting agent onto a nanostructure array formed from a plurality of generally aligned carbon nanotubes or other nanostructures. The condensed wetting agent draws the individual nanostructures together to form various geometries of nanostructured assemblies based on various parameters including process variables and the starting shape and dimensional features of the nanostructure array. Various simple and complex geometries can be achieved in this manner, including geometries that are curved, bent, or twisted. Adjacent nanostructure arrays of the same or different starting geometries can be shaped into compound or interrelating structures. Additional process steps such as plasma etching, coating and others can be used to control the shaping and structural attributes of the nanostructured assemblies. A method of making a molded replica of a shaped nanostructure array is also disclosed.

摘要： Generally, the present invention provides methods for the production of materials comprising a plurality of nanostructures such as nanotubes (e.g., carbon nanotubes) and related articles. The plurality of nanostructures may be provided such that their long axes are substantially aligned and, in some cases, continuous from end to end of the sample. For example, in some cases, the nanostructures may be fabricated by uniformly growing the nanostructures on the surface of a substrate, such that the long axes are aligned and non-parallel to the substrate surface. The nanostructures may be, in some instances, substantially perpendicular to the substrate surface. In one set of embodiments, a force with a component normal to the long axes of the nanostructures may be applied to the substantially aligned nanostructures. The application of a force may result in a material comprising a relatively high volume fraction or mass density of nanostructures. In some instances, the application of a force may result in a material comprising relatively closely-spaced nanostructures. The materials described herein may be further processed for use in various applications, such as composite materials (e.g., nanocomposites). For example, a set of aligned nanostructures may be formed, and, after the application of a force, transferred, either in bulk or to another surface, and combined with another material (e.g., to form a nanocomposite) to enhance the properties of the material.

摘要： The present invention relates to the formation and processing of nanostructures including nanotubes. Some embodiments provide processes for nanostructure growth using relatively mild conditions (e.g., low temperatures). In some cases, methods of the invention may improve the efficiency (e.g., catalyst efficiency) of nanostructure formation and may reduce the production of undesired byproducts during nanostructure formation, including volatile organic compounds and/or polycylic aromatic hydrocarbons. Such methods can both reduce the costs associated with nanostructure formation, as well as reduce the harmful effects of nanostructure fabrication on environmental and public health and safety.
