Polyethylene/polyethylene terephthalate (PE/PET) nonwoven fabrics were first modified with a continuous graphene layer by using a dipping process, and then deposited with silver nanoparticles (AgNPs) by using magnetron sputtering, and that is a novel method called two-step method. Graphene/PE/PET (GPP) and AgNPs sputtered GPP (AGPP) were prepared to investigate the modification processes on the electrical conductivity of the nonwoven fabrics. The influence of the surface modification by silane coupling agent (KH-560) on the durability of conductive PE/PET composited fabrics is also studied. Surface morphology, chemical structure, thermal stability, electrical conductive and ultraviolet protection properties of the composite fabrics were investigated. The results indicated KH-560 treatment can obviously improve the interfacial adhesion between the graphene and PE/PET then contributes to the enhanced conductive durability of the composite fabrics. The combination of graphene and AgNPs provided more opportunities for the charge transfer paths of AGPP, leading to an improved conductive network and an increased electrical conductivity. In addition, graphene and AgNPs gave GPP and AGPP excellent thermal stability. The research exhibited the advantages of the two-step method, and also indicated AGPP has a promising application for the preparation of wearable electronics.
