• Current-voltage electrical behavior of in situ microfibrillar carbon black （CB）/poly（ethylene terephthalate） （PET）/polyethylene （PE） （m-CB/PET/PE） composites with various CB concentrations at ambient temperatures was studied under a direct-current electric field. The current-voltage （l-V） curves exhibited nonlinearity beyond a critical value of voltage. The dynamic random resistor network （DRRN） model was adopted to semi-qualitatively explain the nonlinear conduction behavior of m-CB/PET/PE composites. Macroscopic nonlinearity originated from the interfacial interactions between CB/PET micro fibrils and additional conduction channels. Combined with the special conductive networks, an illustration was proposed to interpret the nonlinear 1-V characteristics by a field emission or tunneling mechanism between CB particles in the CB/PET micro fibers intersections.
