摘要：

For the thin solution film of polyaniline (PAn) and polyacrylic acid (PAA) in 1-methyl-2-pyrrolidone (NMP), the UV-Vis spectra indicate that PAn is not doped, but becomes doped when the same volume of water as that of NMP is added. This is due to the electrostatic interaction and hydrogen bonding between PAA and NMP, the hydrogen bonding between water and NMP, polarity of solvent and entropy of solvation. As a dynamic vacuum is applied, the water is removed first and PAn is dedoped; subsequently, as NMP is removed, PAn becomes doped with PAA.
