Synthesis and structural study of conductive polyaniline using a new method for average mass determination with ultraviolet spectroscopy

In recent years, many advances have been made in the understanding of the conduction mechanisms of conductive polymers. Several reports have highlighted the role of the best characterisation. However, a number of questions remain unanswered. One of the problems is the easy specification of the average mass of polyaniline by UV analyse. The first synthesis of the emeraldine salt is a form doped with hydrochloric acid, and the emeraldine base is the dedoped form of PANI. Then, it was characterised by IR spectroscopy, UV/visible, and compared by GPC chromatography. After calculating the average mass of PANI, it was concluded that new easy UV-visible method is approved by GPC results.
