Offset lithographic printing of nanocomposite graphene ink.

柯式平版印刷机不断用于印刷杂志的高质量光泽彩页。印刷机可以有多种颜色的印刷单元，允许在纸板，纸张和薄塑料上印刷各种图形。该项目的重点是在1000 mm × 707 mm、厚度小于60微米的聚丙烯薄板上进行印刷。商业印刷机在纳米产品母公司成立印刷薄塑料生产模具标签。在高压下迫使聚丙烯熔体进入之前，将这些标签装入注塑模腔。当腔体打开时，标签被结合到注射模制物体的壁中。这通常用于品牌标签食品包装，如酸奶和奶油罐，冰淇淋桶，和快速移动的消费品。希望这个项目的成果将是一种新的导电和导热胶印油墨，它可以与传统的彩色胶印油墨在同一台印刷机上使用。在未来，人们希望印刷石墨烯的功能可以被纳入超级电容器，电池，玩具和游戏，电子防伪标签，并作为柔性光伏器件和显示器的导电层。由于平版印刷的高质量和速度，柔性电子设备和部件的成本可能会显着降低，从而降低价格。除了既定的机会外，还存在在单个柔性基板上打印电力收集、电力存储、传感、驱动、显示和电信设备的战略潜力，以使新的系统级设备能够用于物流，合作伙伴正在共同开发一种新的紫外线固化石墨烯油墨，并测试是否可以将油墨配制成高质量、高速度的胶印。

Offset lithographic printing presses are used continuously to print the high quality glossy colour pages of magazines. Thepresses can have multiple colour print units to allow a vast range of graphics to be printed on cardboard, paper and thinplastics. This project is focused on printing on thin polypropylene sheets which are 1000mm by 707mm and less than 60microns thick. Commercial presses at Nano Products parent company are set up to print on thin plastic to produce in mouldlabels. These labels are loaded into injection moulding die cavity prior to polypropylene melt being forced in at highpressure. When the cavity is opened the label is incorporated into the wall of the injection moulded object. This iscommonly used to brand label food packaging such as yoghurt and cream pots, ice cream tubs, and fast moving consumergoods. It is hoped that the outcome of this project will be a new electrical and thermally conductive offset lithographic inkwhich can be used on the same press with conventional colour offset inks. In the future it is hoped that the printedgraphene features can be incorporated in super-capacitors, batteries, toys and games, electronic anti-counterfeit labels andas the conducting layers in flexible photovoltaic devices and displays. Because of the high quality and speed of offsetlithographic printing there are likely to be significant cost reduction of flexible electronic devices and components, whichwill lead to lower prices. As well as established opportunities there is the strategic potential to print power harvesting, powerstorage, sensing, actuation, display and telecommunications devices on a single flexible substrate to enable new systemslevel devices for logistic, healthcare diagnostics and telecommunications devices to name a few.The collaborative partners are working together to develop a new UV cured graphene ink and to test whether it is feasibleto formulate the ink for high quality, high speed offset printing.
