Abstract Although many studies have investigated the percolation threshold and conductivity in polymer carbon black (CB) nanocomposites (PCBs) by experimental data, modeling this field is a topic previously overlooked literature. This paper suggests simple equation for PCBs surface properties of CB well as interphase depth ( t ). Also, electrical simulated radius R ), tunneling distance λ ) depth. The offered model validated experimented findings numerous samples parametric examinations. A thicker higher interfacial tension positively reduce onset. smaller CBs, lower threshold, tunnels enhance PCBs. low 0.01 obtained (15 nm) thick (35 nm). = 15 nm 35 maximize PCB to 6 S/m. These results signify important roles In addition, network fraction f 0.7 1 produce uppermost 1.6 S/m, but system insulated at less than 0.35 or more 2 nm. Therefore, high are needed Highlights An onset proposed data Smaller onset, conductivity. significantly manage
