Porous fiber formation in polymer-solvent system undergoing solvent evaporation
2006
Journal of Applied Physics
Temporal evolution of the fiber morphology during dry spinning has been investigated in the framework of Cahn-Hilliard equation ͓J. Chem. Phys. 28, 258 ͑1958͔͒ pertaining to the concentration order parameter or volume fraction given by the Flory-Huggins free energy of mixing ͓P. J. Flory, Principles of Polymer Chemistry ͑Cornell University Press, Ithaca, NY, 1953͒, p. 672͔ in conjunction with the solvent evaporation rate. To guide the solvent evaporation induced phase separation, equilibrium
