Abstract

Electrical, morphological and rheological properties of polyethylene (PE)/multi-walled carbon nanotube (MWCNT) and poly(phenylene sulfide) (PPS)/MWCNT composites were studied with the MWCNT content using vector network analyzer, scanning electron microscopy and rotational rheometry. From the results of electrical conductivity and electromagnetic interference shielding efficiency (EMI SE) of the PE/MWCNT and PPS/MWCNT composites, the electrical percolation threshold of the composites has found to be 5 and 3 wt% MWCNT, respectively. From the results of the EMI SE of the composites, it was suggested that the increase in homogeneous dispersion of the MWCNT in the PPS matrix has been attributed to the increase in connectivity of the MWCNT-MWCNT network structure of the composite. Therefore, the higher values of the EMI SE with the MWCNT content were observed in the PPS/MWCNT than the PE/MWCNT composites. From the results of the rheological properties of the PE/MWCNT and PPS/MWCNT composites, the increase in the complex viscosity was observed for the PPS/MWCNT than the PE/MWCNT composites. The increase in complex viscosity maybe due to the increase in homogeneous dispersion of the MWCNT in the PPS matrix than that in the PE matrix. From the results of the rheological properties of the PE/MWCNT and PPS/MWCNT composites, it was suggested that the homogeneous dispersion of the MWCNT in the polymer matrix has affected the increase in complex viscosity of the PPS/MWCNT composite. This result of rheological behavior is consistent with the results of the EMI SE of the PE/MWCNT and PPS/MWCNT composites.
