Summary:

The collection of topics in this book reflect the recent advances in preparation, properties and applications of polyanilines and functionalised polyanilines. Furthermore, this book provides a unique opportunity for readers to explore in one place new and exciting research on nanostructured polyanilines and functionalised polyanilines that has been published recently. It combines a comprehensive review of recent research on polyaniline based conducting polymers with a critical review of the results of this research and detailed descriptions of experimental procedures for the various synthetic methods. In particular, novel methods of synthesis and potential future methods of production of nanostructured polyaniline-based materials for industrial applications, such as enhanced microwave synthesis and electrospinning, are discussed in detail.
