A new way of step-mass-thermal transferring to control phase inversion for polyacrylonitrile(PAN)/DMSO/water system

The step-mass-thermal transferring meant that for PAN/DMSO/water system, the kinetic of phase inversion and droplet ripening was controlled by employing several consecutive coagulation baths with different concentrations and temperatures. In this way, the morphology of fiber could be adjusted based...

Description
Summary:The step-mass-thermal transferring meant that for PAN/DMSO/water system, the kinetic of phase inversion and droplet ripening was controlled by employing several consecutive coagulation baths with different concentrations and temperatures. In this way, the morphology of fiber could be adjusted based on modelling. The phase diagram of PAN/DMSO/water was calculated based on Flory-Huggins theory. The mass and thermal transferring was calculated according to Fick’s second law and Fourier heat equation respectively.
