Abstract
A nonwoven-based composite that can shield electromagnetic interference (EMI) in contemporary society was successfully fabricated by adhering graphene (GE) nanosheets to nonwoven fabric with polyvinylidene fluoride (PVDF) as the adhesive agent. A cyclic GE dispersion dipping-drying process produced nonwoven composites with increasing GE adsorption, which formed an ever more conductive network and led to improvement in EMI shielding performance. The bonding effects of PVDF between GE nanosheets and nonwoven framework were confirmed via ultrasonic vibration analysis and morphology observation. Composite shielding effects were evaluated in a wide incident frequency from 1 to 18 GHz, which revealed that the overall EMI shielding effectiveness was over 20 dB and this EMI shielding was absorption dominant. Such a composite possessed the potential to be used in household and industrial products for EMI shielding.
