  • Patent number: 10894718
    Abstract: A nanofiber forest is described that has been processed to increase a number of nanofibers per unit area (referred to as “areal density” or, equivalently, “density”) compared to the nanofiber forest in its as-synthesized state. This increase in areal density is accomplished by physically manipulating a deformable substrate on which the nanofiber forest is disposed. At a high level, this physical manipulation begins by transferring the nanofiber forest from a growth substrate to a deformable substrate. A surface area of the deformable substrate is reduced relative to a surface area of the substrate when the nanofiber forest was attached. This reduction in area causes the nanofibers in the forest to move closer to one another, thus increasing the number of nanofibers per unit area.

  • Patent number: 10777367
    Abstract: A fibrous electrode includes a carbon nanotube sheet which is coated on an elastic fiber and has a buckle structure. Thus, the fibrous electrode may maintain a fiber shape, may be light and small and may maintain excellent conductivity even when variously deformed. In addition, the fibrous electrode has high elasticity and thus is capable of being variously deformed (e.g., bent or stretched) and of being realized in the form of textile. As a result, the fibrous electrode may be effectively applied to flexible electronic devices such as implantable medical devices, microelectronic devices, Google glasses, smart watches, wearable computers, and smart clothing. Furthermore, a supercapacitor using the fibrous electrode includes flexible materials and thus is not easily damaged by external force such as tension or pressure. As a result, the supercapacitor may be applied to various fields because of its excellent flexibility.

  • Patent number: 10570293
    Abstract: A method of making CNT films is described in which the film is washed with a mild acid treatment. The method generates a CNT film that is not sensitive to moisture or fluctuations in moisture. The method involves the use of anionic polysaccharides or anionic glycosaminoglycans such as hyaluronic acid, sodium salt, as aqueous dispersing agents and their modification to a hydrophobic matrix after deposition. In the course of conducting the work described here, we made the surprising discovery that washing with an aqueous acidic solution resulted in a decrease in resistance through the material. The invention also includes CNT composites made by the inventive methods and a CNT composite comprising CNTs and anionic polysaccharides or anionic glycosaminoglycans further characterized by a low cationic content and a high conductivity and/or small CNT particle size as measured by SEM.

  • Patent number: 10384200
    Abstract: The present invention relates to a supported catalyst having a structure in which a metal catalyst is supported on a core-shell structured support. The support includes core particles and shell particles having a smaller particle diameter than the core particles and coated on the core particles to form a shell layer. Due to this structure, the supported catalyst can be used to produce carbon nanostructures that form a novel secondary structure in which ends of the carbon nanostructures are supported on the supported catalyst and form independent branches and the opposite ends grow and are assembled together. The novel structure is expected to find application in various fields, such as energy materials, functional composites, pharmaceuticals, batteries, and semiconductors, because of its characteristic shape.
