石墨烯墨水的喷墨印刷被认为对于可穿戴电子纺织品应用非常有前景，因为可以利用喷墨印刷和石墨烯非凡的电子、光学和机械性能的优点。然而，与在纺织品上喷墨印刷导电油墨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，首次使所有喷墨印刷的石墨烯电子纺织品成为可能。功能化的有机纳米粒子在纺织品上呈现出疏水性透气涂层。随后在预处理涂层上喷墨印刷连续导电路径，与未经处理的纺织品相比，将石墨烯基印刷电子纺织品的薄层电阻降低了三个数量级，从 1.09 x 10(6) Omega sq(-1) 到 2.14 x 103 Omega sq(-1)。我们提供了几个例子，说明这一发现如何为印刷、低成本和环保的石墨烯可穿戴电子纺织品的实际应用开辟机会。
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 x 10(6) Omega sq(-1) to 2.14 x 103 Omega 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.
