Abstract

Polypyrrole (PPy) nanowire network plates with both average length and width in tens of micrometers were prepared in an aqueous solution containing cetyltrimethylammonium bromide (CTAB) and nitric acid (HNO~3~) by chemical oxidative polymerization methods. It is found that PPy plates are constructed with double layers of nanowire networks. The influences of recipe such as the concentration of CTAB, HNO~3~, and pyrrole, as well as the reaction temperature on the morphologies of produced PPy were systematically investigated. By control experiment employing H~2~SO~4~ or HCl in place of HNO~3~, it is disclosed that HNO~3~ probably plays a key role in forming PPy plates. A plausible forming mechanism of PPy plate structures is offered. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
