摘要

A convenient and economical method for preparing soluble conductive polyaniline nanoparticles is introduced in this article. Polyaniline (PANI) was prepared by utilizing a renewable resource calcium lignosulfonate (LS) as dopant in the presence (PANILS- M) and absence (PANI-LS-A) of a constant magnetic field (MF). Their structures and properties were systematically studied. Compared with PANI-LS-A, the PANI-LS-M exhibited a much higher conductivity, solubility, and thermo stability, which was due to the effective doping of the LS caused by the stretching and orientation effects of the MF. The conductivity of the PANI-LS-M (20.2 S/ cm), which was prepared in the presence of a MF (0.4 T) with a polymerization yield of as much as 96%, was increased by four times compared with that of the PANI-LS-A (4.9 S/cm). Meanwhile, the solubility of the PANI-LS-M was two times higher than that of the PANI-LS-A in solvents such as NMP, dimethyl sulfoxide, dimethyl formamide, formic acid, and acetidin.
