development of wearable electronics creates demands to fulfill
requirements such as shielding electromagnetic radiation to reduce
its harmful side effects on humans and electronic equipment. Here,
wearable substrates/electrodes were fabricated through simple and
cost-effective fabrication procedures showing high-performance electromagnetic
interference shielding and excellent antibacterial activities. Silver
nanoparticles were sputtered on one side and graphene oxide (GO) was
sprayed on the other side of a nylon/polyester fabric, followed by
chemical reduction. The durability of the modified fabric was investigated
under mechanical deformation. A high electrical conductivity of the
fabric causes great microwave attenuation in the X-band and part of
the S-band. Electrochemical performances of the composites as electrodes
in wearable electronics were investigated. The antibacterial activities
of the modified fabrics were excellent against Escherichia
coli and Staphylococcus aureus, and the modified fabrics showed great durability even after 50 washing
cycles. Having high-performance microwave shielding and biocidal properties
makes an Ag/reduced GO fabric a potential candidate to be used as
wearable electronics.
