and the subsequent pyrrole modification. CuNWs were prepared using hydrothermal method. The results showed that the combination of PPy-MXene and CuNWs can synergistical enhanced the mechanical, electrical conductivity, and electromagnetic interference (EMI) shielding performaces of the rubber nanocomposites. The composite filled with 1 wt% of PPy-MXene and 5 wt% of CuNWs (28.35 dB) exhibits higher shielding efficiency than that filled by just one type of nanofillers at the same loading, and the shielding of electromagnetic waves mainly relies on absorption loss due to synergistic effect and the formation of a more complete network structure of PPy-MXene and CuNWs.
