▎ 摘 要
NOVELTY - A printed electronic device comprises a substrate comprising at least one surface, where a layer of an electrically conductive ink has been applied to a portion of the surface, and the ink comprises functionalized graphene sheets and at least one binder. USE - As printed electronic device in the form of an integrated circuit; printed circuit board; light-emitting diode display; radiofrequency identification device (RFID) and/or radiofrequency device antenna for use with ultra-high frequencies (all claimed) 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; electrical and electronic circuitry, transistors, field-effect transistors, microelectromechanical systems (MEMS) devices, microwave circuits, antennas, indicators, chipless tags, smart cards, sensors, liquid crystalline displays (LCDs), signage, lighting, flat panel displays; flexible displays, including light-emitting diode, organic light-emitting diode (OLED), and polymer light-emitting diode displays; backplanes and frontplanes for displays, electroluminescent and OLED lighting, photovoltaic devices-backplanes, product identifying chips and devices; batteries, including thin film batteries, electrodes, indicators, printed circuits in portable electronic devices (e.g. cellular telephones, computers, personal digital assistants, global positioning system devices, music players, games and calculators); electronic connections made through hinges or other movable/bendable junctions in electronic devices such as portable computers and folding keyboards; wearable electronics; circuits in vehicles, medical devices, diagnostic devices and instruments. ADVANTAGE - The ink provides film on surface of substrates, which provides excellent peel resistance and scratch resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for forming a printed electronic device involves applying an electrically conductive ink comprising functionalized graphene sheets and binder to a substrate.
