Abstract

The formation of segregated conductive networks is significantly important for achieving excellent electromagnetic interference (EMI) shielding performance in a conductive polymer composite. Nevertheless, the low melt viscosity of poly(phenylene sulfide) (PPS) would lead to intense diffusion between the conductive filler and PPS molecular chains, which disturbs the selective distribution of the conductive filler to form a segregated structure. Herein, sinter molding was first utilized to control the selective distribution of carbon nanotubes (CNTs) among the interfaces of PPS domains and facilely construct a segregated structure in the resultant CNT/PPS composite. The segregated CNT/PPS composite with only 5.0 wt% CNTs exhibits a very high electrical conductivity of 72.0 S m−1 and EMI shielding effectiveness (EMI SE) of 49.6 dB. Our work provides insight into the development of highly efficient and heat resistant EMI shielding materials via a novel processing method.
