Residual water as a factor influencing the electrical properties of polyaniline. The role of hydrogen bonding of the polymer with solvent molecules in the formation of a conductive polymeric network
TL;DR: In this paper, the influence of residual water retained in the emeraldine base form of polyaniline (PANI-EB) on its electrical properties (dielectric losses, complex electric modulus and impedance) is studied in the frequency range 10-105 Hz.

Polyaniline Membranes for Pervaporation of Carboxylic Acids and Water
TL;DR: In this paper, free-standing polyaniline films are studied as pervaporation membranes for separating carboxylic acid/water mixtures. But the results show that the improved selectivity of the doped, acid form is due in part to the hydrophilicity induced in the polymer by the acid dopants.

The structure of a novel polymeric metal: Acceptor-doped polyaniline
TL;DR: In this article, the same authors deduced key structural features of acceptor-doped polyaniline (polyemeraldine salt) from the crystal structures for the ClO 4 − and the BF 4 − dication salts of H(C 6 H 4 ǫ NH 6 H 6 H 5, radical cation salts of shorter oligomers and neutral H 5 C 6 C 6 NC 6H 4 NNH 6 H5, and showed that radical cations are
