Hollow Nanostructured Polyaniline: Preparation, Properties and Applications

In the last decade, hollow polyaniline nanostructures such as nanocapsules and nanotubes have attracted increasing attention due to their potential applications in electrical and optoelectronic nanodevices, sensors, supercapacitors, energy storage devices, and else where. Many strategies have been developed for their preparation, such as hard template methods with physical templates, soft template methods with chemical templates, and template-free methods. The present status and future directions of hollow Polyaniline nanostructures using these pathways are described in this review. Their properties and applications are also addressed. Finally, the review examines developing perspectives for the future application of nanostructures.
