We have found that polymer poly (sodium 4‐styrenesulfonate) (PSS) is a facile and effective polymer to assist in the dispersion of MWCNTs in aqueous solutions. With the increase of the concentration of PSS solutions, the dispersibility of MWCNTs in PSS solution increases. Cast films of MWCNTs/PSS (2 wt.%) on GC electrode show a typical redox couple at scan rate of 1 V/s in phosphate buffer solution, indicating good electrical conductivity.
