摘要: The invention discloses equipment and preparation method for open and continuous growth of a carbon nanomaterial. The equipment comprises a metal foil tape feeding system, a CVD system and a collection system. The method includes continuously conveying a metal foil tape pretreated or not into the CVD system via the metal foil tape feeding system, depositing a required carbon nanomaterial on the surface of the metal foil tape by CVD, directly collecting by the collection system or directly post-treating the carbon nanomaterial by a post-treatment system, and even directly producing a end product of the carbon nanomaterial. All the systems in the invention are arranged in the open atmosphere rather than an air-isolated closed space. The invention can realize round-the-clock continuous operation to greatly improve the production efficiency of carbon nanomaterials.

摘要: A method of producing graphene or other two-dimensional material such as graphene including heating the substrate held within a reaction chamber to a temperature that is within a decomposition range of a precursor, and that allows two-dimensional crystalline material formation from a species released from the decomposed precursor; establishing a steep temperature gradient (preferably >1000° C. per meter) that extends away from the substrate surface towards an inlet for the precursor; and introducing precursor through the relatively cool inlet and across the temperature gradient towards the substrate surface. The steep temperature gradient ensures that the precursor remains substantially cool until it is proximate the substrate surface thus minimizing decomposition or other reaction of the precursor before it is proximate the substrate surface. The separation between the precursor inlet and the substrate is less than 100 mm.

摘要: Multilayer structures comprising a covalent organic framework (COF) film in contact with a polyaromatic carbon (PAC) film. The multilayer structures can be made by combining precursor compounds in the presence of a PAC film. The PAC film can be for example, a single layer graphene film. The multilayer structures can be used in a variety of applications such as solar cells, flexible displays, lighting devices, RFID tags, sensors, photoreceptors, batteries, capacitors, gas-storage devices, and gas-separation devices.
