Porous polyvinylidenefluoride (PVDF) hollowfibermembranes were fabricated via a wet phase-inversion method. Ortho-phosphoric acid and lithium chloride monohydrate (LiCl·H2O) were used as phase-inversionpromoteradditives in the spinning dopes. Ternary phase diagram of the polymer dopes were obtained...
