Abstract

Aqueous dispersions of polyaniline were synthesized in the presence of various surfactants. Polyvinyl alcohol and polymeric surfactants with various chain lengths of polyoxyethylene fragments served as stabilizers. It was shown that it is advisable to use polymeric surfactants with side polyoxyethylene fragments to improve the sedimentation stability of aqueous dispersions of polyaniline. It was found that the particle size distribution of aqueous dispersions depends on the composition of the stabilizer used. Raising the pH value of aqueous dispersions to 8 makes it possible to substantially raise the sedimentation stability. The effect of a surfactant used to stabilize the dispersed system on the electrokinetic potential was examined.
