▎ 摘 要
NOVELTY - Nano-graphene oxide sheets or nano-graphene sheets having a maximum average lateral dimension of 100 nm. USE - As nano-graphene oxide sheets or nano-graphene sheets (claimed) used in electrical and electronic devices and components including portable electronic devices such as computers, cellular telephones, games, navigation systems, personal digital assistants, music players, games, calculators, radios, artificial "paper" and reading devices; in printed electronic devices, passive and active devices and components; electrical and electronic circuitry, integrated circuits; flexible printed circuit boards; transistors; field-effect transistors; microelectromechanical systems (MEMS) devices; microwave circuits; antennas; diffraction gratings; indicators; chipless tags; security and theft deterrence devices for retail, library, and other settings; key pads; smart cards; sensors; liquid crystalline displays; signage; lighting; flat panel displays; flexible displays, including light-emitting diode, organic light-emitting diode, and polymer light-emitting diode displays; backplanes and frontplanes for displays; electroluminescent lighting; photovoltaic devices, including backplanes; product identifying chips and devices; membrane switches, batteries, including thin film batteries; electrodes; indicators; printed circuits in portable electronic devices; wearable electronics; and circuits in vehicles, medical devices, diagnostic devices, instruments; in radiofrequency identification (RFID) devices and/or their components and/or radiofrequency communication device used for tracking shipping containers, products in stores, products in transit, and parts used in manufacturing processes; passports; barcode replacement applications; inventory control applications; pet identification; livestock control; contactless smart cards; and automobile key fobs. ADVANTAGE - The nano-graphene oxide sheets or nano-graphene sheets have an average maximum lateral dimension of about 5 nm, and this smaller lateral dimensions make them suitable for large scale production methods. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) making nano-graphene oxide sheets involving oxidizing at least one carbonaceous material having graphitic domains; and (2) making nano-graphene sheets involving reducing nano-graphene oxide sheets having a maximum average lateral dimension of about 50 nm.
