Abstract
An epoxy/PEI/carbon coating was developed containing differing amounts of graphene or graphite to impart electrical conductivity onto a nonwoven viscose textile. It was found that an increase in carbon filler content resulted in increased electrical conductivity and that multiple coatings improved electrical conductivity further. Decyl glucoside surfactant improved particle mixing without influencing electrical conductivity. The coated material exhibited a minimum electrical resistivity in the megaohm range which makes it a relatively weak electrical conductor, however it can be considered as antistatic. The samples indicated no EMI shielding in the 30 MHz - 3 GHz range.
