Abstract
The effects of electrolytes and surfactants on the hydrodynamic charac teristics of polyacrylonitrile (PAN) in dimethylformamide (DMF) were e xamined using viscometry and photon correlation spectroscopy. It was f ound that inorganic electrolytes show a strong salting-out effect on P AN in DMF. Cationic surfactants were also found to affect the hydrodyn amic characteristics of PAN in a DMF solution, whereas the effect of a nionic surfactants was almost inconspicuous. The effect of surfactants on structuration of PAN in DMF is discussed within the framework of t he fractal concept.
