中文摘要：

打印过程的一系列 inkjet 用基于 graphene 的墨水被学习了。在优化条件下面，使用水溶性的单人赛分层的 graphene 氧化物(去)并且很少分层的 graphene 氧化物( FGO )，各种各样的高图象质量模式能在多样的灵活底层上被打印包括纸， poly (乙烯 terephthalate )(宠物)并且 polyimide ( PI )，与打印技术的简单、便宜的 inkjet 。在塑料底层上打印的基于 graphene 的模式在热减小以后表明了高电的传导性，并且更重要地，他们在严重弯曲周期上保留了一样的传导性。因此，灵活电的电路和一个氢过氧化物化学药品传感器被制作并且显示出优秀表演，演示打印用 graphene 墨水的技术的这简单、实际的 inkjet 的应用程序。结果显示出那 graphene 材料 -- 它能容易在大规模上被生产并且为灵活、便宜的基于 graphene 的电子设备的方便制造拥有突出的电子性质有伟人潜力，由使用打印技术的简单 inkjet。

英文摘要：

A series of inkjet printing processes have been studied using graphene-based inks. Under optimized conditions, using water-soluble single-layered graphene oxide （GO） and few-layered graphene oxide （FGO）, various high image quality patterns could be printed on diverse flexible substrates, including paper, poly（ethylene terephthalate）（PET） and polyimide （PI）, with a simple and low-cost inkjet printing technique. The graphene-based patterns printed on plastic substrates demonstrated a high electrical conductivity after thermal reduction, and more importantly, they retained the same conductivity over severe bending cycles. Accordingly, flexible electric circuits and a hydrogen peroxide chemical sensor were fabricated and showed excellent performances, demonstrating the applications of this simple and practical inkjet printing technique using graphene inks. The results show that graphene materials--which can be easily produced on a large scale and possess outstanding electronic properties--have great potential for the convenient fabrication of flexible and low-cost graphene- based electronic devices, by using a simple inkjet printing technique.
