摘要

Electronic textiles (e-textiles),known as a newly-developed innovation combining the textile and electronic technologies,are burgeoning as the next-generation of wearable electronics for lots of promising applications.However,a big concern is the durability of the e-textilss during practical using.Here,we describe a facile method to fabricate mechanically and electrically durable e-textiles by chemical deposition of silver nanoparticles (AgNPs) on widely used cotton fabric.The interface between AgNPs and fabric was tightly strengthened by the bioinspired polydopamine,and a highly waterproof and anticorrosive surface was further obtained by modifying with a fluorine containing agent of 1H,1H,2H,2H-perfuorodecanethiol (PFDT).In addition to the low sheet resistance of 0.26 ohm/sq and high conductivity of 233.4 S/cm,the e-textilss present outstanding stability to different mechanical deformations including uitresonication,bending and machine washing.Moreover,thanks to the surface roughness of AgNPs and low surface energy of PFDT,a superhydrophobic surface,with a water contact angle of ca.152°,was further obtained,endowing the e-textiles excellent anti-corrosion to water,acid/alkaline solution and various liquids (e.g.,milk,coffee and tee).Finally,the application of this highly conductive e-textiles in wearable thermal therapy is demonstrated.Together with the facile,all-solution-based,and environmentally friendly fabrication protocol,the e-textiles show great potential of large-scale applications in wearable electronics.
