A New Way of Step-mass-thermal Transferring to Control Phase Separation for Polyacrylonitrile (PAN)/DMSO/Water System

摘要：

The step-mass-thermal transferring for PAN/DMSO/Water system was proposed to control the kinetic of phase separation and droplet ripening. In this way, the morphology of fiber could be regulated by employing several consecutive coagulation baths with different concentrations and temperatures based on modelling. Phase diagram of ternary system about PAN/DMSO/water was calculated according to Flory-Huggins theory. The mass and thermal transferring was calculated using Ficks second law and Fourier heat equation respectively.
