Multilayer-Structured Polypyrrole/Reduced Graphene Oxide Composite Silk Fabric Based on Self-Assembly Method for Electromagnetic Interference Shielding

The electromagnetic wave radiation of smart wearable clothing poses serious harm to the human body. However, short-process and low-energy-consuming wearable clothing still faces challenges that hinder the widespread use of electromagnetic interference shielding. Herein, a reduced graphene oxide and pyrrole composite silk fabric (PPy-rGO-SF) has been developed through a facile self-assembling process. As a result, the as-obtained fabric possesses an excellent electrical conductivity of 0.141 kΩ/cm and outstanding electromagnetic interference shielding efficiency of 90% owing to the synergistic enhancement effect of reduced graphene oxide (rGO) and polypyrrole (PPy). Moreover, the electromagnetic interference shielding fabric possesses good stability, which still maintains the same electromagnetic shielding performance of 90% after undergoing 30 cycles of mechanical deformation tests. These findings offer a potential capacity for smart wearable clothing and electromagnetic interference shielding products.
