Abstract

In this study, silver/reduced graphene oxide (Ag/RGO) coated polyester (PET) fabrics with dopamine as adhesive agent were prepared through an efficient chemical reduction method under microwave irradiation. The as-synthesized samples were characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and scanning electron microscopy. Deposit weight, surface resistance and electromagnetic interference (EMI) shielding effectiveness (SE) of the Ag/RGO coated PET fabric were investigated. The dopamine modified PET fabric is covered with silver particles and reduced graphene oxide (RGO) sheets uniformly and densely. In addition, the Ag/RGO coated fabric possesses high electrical conductivity with low surface resistance of 0.678 Ω sq-1and EMI SE of Ag/RGO coated fabric ranges from 58 dB to 65 dB in the range of 1-18 GHz X-band. Adhesive strength between Ag/RGO particles and PET fabric is significantly improved.
