Structure and properties of polyaniline interacting with H-phosphonates
Original language description
Polyaniline (PANI) is conducting when doped, typically with an acid. However, acids are not the only species able to dope PANI. In this study, we show that non-conducting PANI base powder interacts with dimethyl H-phosphonate (DMPH), diethyl H-phosphonate (DEPH), dibutyl H-phosphonate (DBPH) and diphenyl H-phosphonate (DPPH) and yields conducting adducts. The highest conductivity 0.23 S cm-1 is observed for DPPH. The samples were analyzed by FTIR, Raman, NMR, and EPR spectroscopies. We have shown that the doping of PANI with H-phosphonates is only partial and at least part of DEPH and DPPH molecules preserves the H-phosphonate structure, in contrast with DMPH and DBPH. We have also correlated the information on polaron delocalization and mobility obtained from Raman and EPR spectra – polarons in the PANI adduct with DEPH and DPPH have higher mobility. This paper represents a comparative study of a class of PANI-based materials and shows a connection between chain conformation of PANI and materials properties.
