Inkjet printing of graphene inks is considered to be very promising for wearable e-textile applications as benefits of both inkjet printing and extra-ordinary electronic, optical and mechanical properties of graphene can be exploited. However, the common problem associated with inkjet printing of conductive inks on textiles is the difficulty to print a continuous conductive path on a rough and porous textile surface. Here we report inkjet printing of an organic nanoparticle based surface pre-treatment onto textiles to enable all inkjet-printed graphene e-textiles for the first time. The functionalized organic nanoparticles present a hydrophobic breathable coating on textiles. Subsequent inkjet printing of a continuous conductive electrical path onto the pre-treated coating reduced the sheet resistance of graphene-based printed e-textiles by three orders of magnitude from 1.09 × 10⁶ Ω sq⁻¹ to 2.14 × 10³ Ω sq⁻¹ compared with untreated textiles. We present several examples of how this finding opens up opportunities for real world applications of printed, low cost and environmentally friendly graphene wearable e-textiles.

适用于可穿戴电子纺织应用的所有喷墨印刷的基于石墨烯的导电图案

石墨烯油墨的喷墨印刷被认为对于可穿戴电子纺织应用是非常有前途的，因为可以利用喷墨印刷的益处以及石墨烯的非凡的电子，光学和机械性能。然而，与在纺织品上进行导电油墨的喷墨印刷相关的常见问题是难以在粗糙且多孔的纺织品表面上印刷连续的导电路径。在这里，我们报告了基于有机纳米颗粒的表面预处理在纺织品上的喷墨印刷，从而首次实现了所有喷墨印刷的石墨烯电子纺织品的生产。功能化的有机纳米颗粒在纺织品上呈现出疏水透气的涂层。⁶ Ω平方^-1至2.14×10³ Ω平方^-1与未处理的纺织比较。我们提供了一些示例，说明这一发现如何为印刷，低成本和环保石墨烯可穿戴电子纺织品在现实世界中的应用创造机会。
