Abstract: A facile strategy for fabricating the polypyrrole-β-cycledextrin (PPy-CD) nanospheres with a unique coreshell structure was presented in this paper. The prepared nanospheres have a uniform nano-size with a narrow size distribution. The PPy-CD nanospheres were successfully synthesized via a simple ultrasonic treatment by mixing pyrrole and β-cycledextrin (β-CD) in the ethanol/aqueous solution at room temperature, and FeCl3 was added as an oxidant. With the aid of FeCl3, a continuous polypyrrole (PPy) layer was formed on the surface of β-CD through the oxidative polymerization of pyrrole. These PPy-CD nanospheres were extensively characterized by scanning electronic microscopy (SEM) and transmission electron microscopy (TEM). It was found that the prepared PPy-CD nanospheres have a clear coreshell nanostructure.
