All Inkjet-printed Graphene-based Conductive Pattern for Wearable E-textiles Application

Abstract

Inkjet printing of graphene inks are considered to be very promising for wearable e-textiles 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 ink on textiles is the difficulty to print continuous conductive path on a rough and porous textiles surface. Here we report inkjet printing of an organic nanoparticles based surface pre-treat 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 continuous conductive electrical path onto the pre-treat coating reduced the sheet resistance of graphene-based printed e-textiles by three orders of magnitude from 1.09 × 10E6 Ω/sq. to 2.14 × 10E3 Ω/sq compared with untreated textile. We present several examples how this finding opens up opportunities for real world applications of printed, low cost and environmentally friendly graphene wearable e-textiles.
