Offset lithographic printing of nanocomposite graphene ink

胶印平版印刷机用于印刷杂志上的光面彩色页面。该印刷机有许多彩色油墨配方，可用于在纸板、纸张和薄塑料上打印各种图形。该项目将在1000 mm×707 mm×0.060 mm厚的柔性塑料薄片上打印石墨烯。印刷元件将用于印刷电子应用，用作食品和工业包装的阻隔层，以及电池、超级电容器和电化学传感器、玩具和游戏、电子防伪标签的电极，以及柔性光伏设备和显示器的导电层。由于胶印平版印刷的高质量和高速度，柔性电子设备和组件的成本可能会显著降低，这将导致更低的价格。除了现有的机会，还有在单一柔性基板上打印电力采集、电力存储、传感、驱动、显示和电信设备的战略潜力，以实现用于跟踪、医疗诊断和无线设备的智能标签，这些设备保存客户感兴趣的信息。

Offset lithographic printing presses are used to print glossy colour pages in magazines. The presses have many colour inks formulations which can be used to print a vast range of graphics on cardboard, paper and thin plastics. This project will print graphene on to thin flexible plastic sheets, 1000mm by 707mm by 0.060 mm thick. Printed components will be used in printed electronics applications, as barrier layers for food and industrial packaging and electrodes for batteries, super capacitors and electrochemical sensorss, toys and games, electronic anti-counterfeit labels and as the conducting layers in flexible photovoltaic devices and displays. Because of the high quality and speed of offset lithographic printing there are likely to be significant cost reduction of flexible electronic devices and components, which will lead to lower prices. As well as established opportunities there is the strategic potential to print power harvesting, power storage, sensing, actuation, display and telecommunications devices on a single flexible substrate to enable SMART labels for tracking, healthcare diagnostics and wireless devices which hold information of interest to a customer.
