Abstract

The effect of Graphite Nanoplates (GnPs) and Expanded Graphite (EG) on electrical and rheological properties was investigated in co-continuous melt-mixed polycarbonate (PC) /poly(styrene-Acrylonitrile) = 60/40 wt% prepared using micro-compounder in two steps. Mixing conditions in premixing the fillers into PC were varied. Similar to carbon nanotubes (CNTs), GnPs and EG tend to localize in PC. Improved filler dispersion for samples exposed to higher mixing energy in the premixing step resulted in larger increase of complex viscosity and storage modulus. However, electrical resistivity was lower in samples which experienced lower mixing energy. Comparing EG and GnP, the effects are quite similar. EG showed a slightly better electrical performance.
