| Abstract: | Epoxy resin(EP)/polycarbonate(PC)/carbon black(CB) ternary composites and EP/CB binary composites were prepared by solution blending method.The microstructure and electrical properties of the composites were investigated by using scanning electron microscopy,optical microscopy,precision impedance analyzer and megohm meter respectively.The results showed that PC was more compatible to CB than EP in thermodynamics,thus PC played a role like a surfactant in the EP/PC/CB composite;the addition of PC significantly improved the dispersion of CB particles in the composite,and could help to form the better conductive networks.Accordingly,PC significantly increased the conductivity,dielectric constant and dielectric loss of the EP/CB composite. |
