摘要：

Polyaniline (PANI) doped by three lignosulfonates (LGSs) with ions of sodium, calcium, and magnesium, respectively, was fabricated and compared. Results showed that the conductivity, solubility, and thermal stability of all these three LGSs-doped PANIs were enhanced, especially the LGS-Ca-doped PANI, when compared with the pure PANI. XRD, UV, and FTIR spectra indicated that the PANI doped by LGS-Ca facilitated electron delocalization, which enhances crystallization of PANI/LGS-Ca with respect to the other two LGSs-doped PANIs. The PANI/LGS-Ca has the best thermal behavior with respect to the other two LGSs-doped PANIs due probably to the hydrogen bonding between LGS-Ca and PANI stable than that between the other two LGSs and PANI.
