High porosity and strong hydrophobicity of polymeric hollow fiber membranes are of great
interest for membrane distillation (MD). Poly(tetrafluoroethylene–cohexafluoropropylene)
(FEP) exhibits excellent chemical resistance, thermal stability, strong hydrophobicity owing
to the perfluoro-structure. Comparing with polytetrafluoroethylene (PTFE), the meltable
property endows FEP good processability for fabricating hollow fiber membrane by meltspinning
method. In our previous articles, FEP hollow fiber membranes have been fabricated
successfully by melt spinning method for the first time. In this study, the effect of the dioctyl
phthalate (DOP) content on the performance and morphology of FEP hollow fiber membrane
was discussed. And the hollow fiber membranes’ properties in terms of porosity, liquid entry
pressure (LEP), mean pore size and also morphologies were characterized, respectively.
