Conductive filler loading in the polymer matrix is a common practice to transform insulative polymers to conducting composites. In case of textiles, the highly promising approach has been coined by virtue of fabricating with conductive adhesive homogeneous coating. The present fabrication approach has been developed by two-stage wet mixing technique including synthesis of silver nanoparticles decorated graphene sheets (rGO/Ag), followed by the preparation of conducting coating by non-ionic polymer adhesive. The novelty lies in the choice of conductive material and coating strategy to make lightweight and flexible smart electronic fabric. In order to protect the radiation pollution from the immense use of electronic devices and gadgets, the coated textiles can be an excellent replacement of other commercially available polymer coatings. The electromagnetic interference (EMI) shielding effectiveness of the prepared coated textile was 27.36 dB in the X band (8.2–12.4 GHz). Besides this it is worth mentioning that our developed coated fabric was enough conductive to light up a series of 57 LEDs with high intensity. Last but not the least this work also reconnoitres bactericidal feature against E. coli.
