| Abstract: | The modified epoxy resin was subsequently blended with graphite/carbon black to generate a conductive composite.The mechanisms of composite were analyzed.The relationship between electrical conduction and filler content was studied.The experimental results indicated that the resistivity of the composite with 15% graphite and 20% carbon black was up to 16.4Ω·cm,the voltage-current characteristic of the conductive composites showed a nonlinear behavior,the composite possessed a notable positive coefficient(PTC). |
