Sodium dodecyl benzene sulfonates were used as a surfactant to obtain
polyacrylonitrile nanofibers by a modified bubble-electrospinning using a
copper cone-shaped air nozzle. The properties of the electrospun solutions
were investigated using viscosity meter, conductivity meter and rheometer,
and the effects of sodium dodecyl benzene sulfonates concentration on the
morphology, mechanical property and production of polyacrylonitrile
nanofibers were studied. The results showed the addition of sodium dodecyl
benzene sulfonates could effectively decrease the viscosity of the
solution, increase the electric conductivity of the solution, and promote
the generation of bubbles, which resulted in enhancing tensile strength and
decreasing the production of nanofibers.
