摘要：

Size control of polypyrrole particles prepared by chemical polymerization was achieved by varying the concentration of the oxidant in the presence of poly(styrenesulfonate). At higher concentrations, smaller polypyrrole particles are formed. Poly(styrenesulfonate) functions as a molecular template, causing local preconcentration of both pyrrole and Fe3+. These increased local concentrations result in faster nucleation and polymerization, which favors the formation of small particles. Average particle sizes ranging from ca. 40 nm to 1 mu m have been obtained.
