Polyaniline (PAni), an interesting conducting polymer (CP), has attracted great attention over the last decades due to its tuneable properties and potential applications in multidisciplinary areas. It is the most promising conducting polymer because of its ease of synthesis, low-cost monomer, and also its higher thermal stability compared to other CPs. This book provides a comprehensive review of the recent trends on PAni research. It is an excellent reference book which covers the latest research on PAni synthesis, properties and applications, from researchers across various disciplines including physics, chemistry, materials science, nanoscience and engineering, based on their expertise in these fields. This book is a true attempt to make available the recent developments in PAni synthesis, properties, and its application, in a single volume and can be recommended as a special reference book for physicists, chemists, material scientists, nanotechnologists, engineers and graduate students.
