Abstract

Abstract : In this study, electroless nickel-plated carbon fiber (CF) was prepared with edge-selectively oxidized graphene (EOG) to reinforce the interface between nickel and CF for use in a composite for electromagnetic interference (EMI) shielding. The EOG layer was formed by generating ionic interaction through a modified layer-by-layer assembly between negatively charged EOG and positively charged polyethyleneimine (PEI). EOG-coated CFs with rough surfaces improved the specific surface area and adhesion strength with the nickel-plating layer. To evaluate the adhesion strength, the interfacial shear strength (IFSS) was investigated using microdroplet testing. After EOG coating, the interfacial bonding strength was enhanced by about 65%. The composite nickel-plated carbon fabric with EOG coating showed EMI shielding of around 58 dB, which is significant for future EMI shielding applications.
