In the filler of conductive material, among the available fillers, CB has been used extensively because of the relative advantages of technology, low cost, and high conductivity properties. In this investigate to use conductive material is nano carbon black(VXC72), but carbon black due to aggregation behavior, account for the difficult in the industry like spinning when carbon black agglomerate too large which make the spin pack of sieve to choke and then can not spinning favorably, the spinning process must to stop. To obtain a well dispersed carbon black matrix, a high-temperature-endurable dispersant and a special two-screw extruder are two crucial issues. In this investigate, we used the copolymer which contain sulfonate(SO3-) and solubility in the water. Due to the dispersant has high-temperature-endurable
