A series of conductive polymers such as polyaniline (PAn) and polypyrrole (PPy) are the most investigated conductive polymers because they have higher conductivity, a good stability in the air and they can be prepared easily. But the special chain structure leads to poor processibility, which limits their more widespread application.First, in this dissertation conductive PAn is prepared, using situ-doped emulsion polymerization. Through studying the influence of the amount of dodecylbenzene sulfuric acid (D...
