Abstract
Graphene oxide-deposited carbon fiber (GO-CF) was obtained by introducing GO onto CF surface through electrophoretic deposition method. GO-CF was found to be more effective than CF in providing electromagnetic interference shielding of cement-based composites. With 0.4wt.% GO-CF and a shield thickness of 5mm, a shielding effectiveness of 34dB was attained at X-band region (8.2–12.4GHz), which had a 31% increase than that of CF/cement (26dB) in the same mass fraction. The GO-CF is believed a promising filler of cement-based composites for high electromagnetic interference shielding.
