Structural properties of polyaniline protonated with camphorsulfonic acid

Polyaniline protonated with camphorsulfonic acid (PANI/CSA) exhibits very interesting processing and electrical transport properties. A series of more than 30 samples prepared in various conditions was subjected to the X-ray diffraction measurements. The influence of the synthesis parameters on the structure of the polymer was investigated. Some correlations between the sample preparation process and its structural properties have been obtained. Besides, new conclusions concerning the model of the crystalline structure of PANI/CSA have been proposed.
