From: First-principles study of the effect of functional groups on polyaniline backbone
The finite molecular models with one polymer monomer for EB-PANI, HO-PANI and Na-SPANI: (a) Unprotonated and (b) H2CO3-protonated states.
The hydrogen, carbon, nitrogen, oxygen, sulfur and sodium atoms are shown in white, grey, blue, red, yellow and violet, respectively.
